+
+NVRAM environment variables.
+
+use the command:
+
+setenv <attribute> <value>
+
+type "saveenv" to write to NVRAM.
+
+
+
+II. To boot from a hard drive:
+
+setenv root /dev/hda1
+
+
+III. IP options which configure the network:
+
+ipaddr=<IP ADDRESS OF MACHINE>
+netmask=<NETMASK>
+hostname=mousse
+ethaddr=00:00:10:20:30:44

+
+IV. IP Options which configure NFS Root/Boot Support
+
+root=/dev/nfs
+serverip=<NFS SERVER IP ADDRESS>
+nfsroot=<NFS SERVER IP ADDRESS>:/boot/root-fs
+
+V. U-Boot Image Support
+
+The U-Boot boot loader assumes that after you build
+your kernel (vmlinux), you will create a U-Boot image
+using the following commands or script:
+
+#!/bin/csh
+/bin/touch vmlinux.img
+/bin/rm vmlinux.img
+set path=($TOOLBASE/bin $path)
+set path=($U_BOOT/tools $path)
+powerpc-linux-objcopy -S -O binary vmlinux vmlinux.bin
+gzip -vf vmlinux.bin
+mkimage -A ppc -O linux -T kernel -C gzip -a 0 -e 0 -n vmlinux.bin.gz -d vmlinux.bin.gz vmlinux.img
+ls -l vmlinux.img
+
+
+VI. ONBOARD FLASH Support
+
+FLASH support is provided for the onboard FLASH chip Bootrom area.
+U-Boot is loaded into either the ROM boot region of the FLASH chip,
+after first being boot-strapped from a pre-progammed AMD29F040 PLCC
+bootrom. The PLCC needs to be programmed with a ROM burner using
+AMD 29F040 ROM parts and the u-boot.bin or u-boot.hex (S-Record)
+images.
+
+The PLCC overlays this same region of flash as the onboard FLASH,
+the jumper J100 is a chip-select for which flash chip you want to
+progam. When jumper J100 is connected to pins 2-3, you boot from
+PLCC FLASH.
+
+To bringup a system, simply flash a flash an AMD29F040 PLCC
+bootrom, and put this in the PLCC socket. Move jumper J100 to
+pins 2-3 and boot from the PLCC.
+
+
+Now, while the system is running, move Jumper J100 to
+pins 1-2 and follow the procedure below to FLASH a bootrom
+(u-boot.bin) image into the onboard bootrom region (AMD29LV160DB):
+
+tftp 100000 u-boot.bin
+protect off FFF00000 FFF7FFFF
+erase FFF00000 FFF7FFFF
+cp.b 100000 FFF00000 \$(filesize)\
+
+
+Here is an example:
+
+=>tftp 100000 u-boot.bin
+eth_halt
+eth0: DC21143 Ethernet adapter(bus=0, device=13, func=0)
+DEC Ethernet iobase=0x80000000

+
+
+B. FLASH RAMDISK REGION
+
+FLASH support is provided for an Onboard 512K RAMDISK region.
+
+TThe following commands will FLASH a bootrom (u-boot.bin) image
+into the onboard FLASH region (AMD29LV160DB 2MB FLASH):
+
+tftp 100000 u-boot.bin
+protect off FFF80000 FFFFFFFF
+erase FFF80000 FFFFFFFF
+cp.b 100000 FFF80000 \$(filesize)\
+
+
+
+C. FLASH KERNEL REGION (960KB)
+
+FLASH support is provided for the 960KB onboard FLASH1 segment.
+This allows flashing of kernel images which U-Boot can load
+and run (standalone) from the onboard FLASH chip. It also assumes
+
+The following commands will FLASH a kernel image to 0xffe10000
+
+tftp 100000 vmlinux.img
+protect off FFE10000 FFEFFFFF
+erase FFE10000 FFEFFFFF

+to start the kernel.
+
+Finally, to make this the default boot command, use
+the following commands:
+
+setenv bootcmd bootm ffe10000
+savenv

+ * "At system reset, initialization software must set up the
+ * programmable parameters in the memory controller banks registers
+ * (ORx, BRx, P/LSDMR). After all memory parameters are configured,
+ * system software should execute the following initialization sequence
+ * for each SDRAM device.
+ *
+ * 1. Issue a PRECHARGE-ALL-BANKS command
+ * 2. Issue eight CBR REFRESH commands
+ * 3. Issue a MODE-SET command to initialize the mode register
+ *
+ * Quote from Micron MT48LC8M16A2 data sheet:
+ *
+ * "...the SDRAM requires a 100uS delay prior to issuing any
+ * command other than a COMMAND INHIBIT or NOP. Starting at some
+ * point during this 100uS period and continuing at least through
+ * the end of this period, COMMAND INHIBIT or NOP commands should
+ * be applied."
+ *
+ * "Once the 100uS delay has been satisfied with at least one COMMAND
+ * INHIBIT or NOP command having been applied, a /PRECHARGE command/
+ * should be applied. All banks must then be precharged, thereby
+ * placing the device in the all banks idle state."
+ *
+ * "Once in the idle state, /two/ AUTO REFRESH cycles must be
+ * performed. After the AUTO REFRESH cycles are complete, the
+ * SDRAM is ready for mode register programming."
+ *
+ * (/emphasis/ mine, gvb)
+ *
+ * The way I interpret this, Micron start up sequence is:

+ * sh.c -- a prototype Bourne shell grammar parser

+ * incidentally is a good match to today's BusyBox.
+ *
+ * Copyright (C) 2000,2001 Larry Doolittle <larry@doolittle.boa.org>
+ *
+ * Credits:
+ * The parser routines proper are all original material, first
+ * written Dec 2000 and Jan 2001 by Larry Doolittle.
+ * The execution engine, the builtins, and much of the underlying
+ * support has been adapted from busybox-0.49pre's lash,
+ * which is Copyright (C) 2000 by Lineo, Inc., and
+ * written by Erik Andersen <andersen@lineo.com>, <andersee@debian.org>.
+ * That, in turn, is based in part on ladsh.c, by Michael K. Johnson and
+ * Erik W. Troan, which they placed in the public domain. I don't know
+ * how much of the Johnson/Troan code has survived the repeated rewrites.
+ * Other credits:
+ * simple_itoa() was lifted from boa-0.93.15
+ * b_addchr() derived from similar w_addchar function in glibc-2.2
+ * setup_redirect(), redirect_opt_num(), and big chunks of main()
+ * and many builtins derived from contributions by Erik Andersen
+ * miscellaneous bugfixes from Matt Kraai
+ *
+ * There are two big (and related) architecture differences between
+ * this parser and the lash parser. One is that this version is
+ * actually designed from the ground up to understand nearly all
+ * of the Bourne grammar. The second, consequential change is that
+ * the parser and input reader have been turned inside out. Now,
+ * the parser is in control, and asks for input as needed. The old
+ * way had the input reader in control, and it asked for parsing to
+ * take place as needed. The new way makes it much easier to properly
+ * handle the recursion implicit in the various substitutions, especially
+ * across continuation lines.
+ *
+ * Bash grammar not implemented: (how many of these were in original sh?)
+ * $@ (those sure look like weird quoting rules)
+ * $_
+ * ! negation operator for pipes
+ * &> and >& redirection of stdout+stderr
+ * Brace Expansion
+ * Tilde Expansion
+ * fancy forms of Parameter Expansion
+ * aliases
+ * Arithmetic Expansion
+ * <(list) and >(list) Process Substitution
+ * reserved words: case, esac, select, function
+ * Here Documents ( << word )
+ * Functions
+ * Major bugs:
+ * job handling woefully incomplete and buggy
+ * reserved word execution woefully incomplete and buggy
+ * to-do:
+ * port selected bugfixes from post-0.49 busybox lash - done?
+ * finish implementing reserved words: for, while, until, do, done
+ * change { and } from special chars to reserved words
+ * builtins: break, continue, eval, return, set, trap, ulimit
+ * test magic exec
+ * handle children going into background
+ * clean up recognition of null pipes
+ * check setting of global_argc and global_argv
+ * control-C handling, probably with longjmp
+ * follow IFS rules more precisely, including update semantics
+ * figure out what to do with backslash-newline
+ * explain why we use signal instead of sigaction
+ * propagate syntax errors, die on resource errors?
+ * continuation lines, both explicit and implicit - done?
+ * memory leak finding and plugging - done?
+ * more testing, especially quoting rules and redirection
+ * document how quoting rules not precisely followed for variable assignments
+ * maybe change map[] to use 2-bit entries
+ * (eventually) remove all the printf's

+New Config Switches:
+====================
+For detailed description, refer to the corresponding paragraph in the
+section "Changes".
+
+New Commands:
+-------------
+CFG_CMD_SCSI SCSI Support
+CFG_CMF_FDC Floppy disk support
+
+IDE additions:
+--------------
+CONFIG_IDE_RESET_ROUTINE defines that instead of a reset Pin,
+ the routine ide_set_reset(int idereset) is used.
+ATAPI support (experimental)
+----------------------------
+CONFIG_ATAPI enables ATAPI Support
+
+SCSI support (experimental) only SYM53C8xx supported
+----------------------------------------------------
+CONFIG_SCSI_SYM53C8XX type of SCSI controller
+CFG_SCSI_MAX_LUN 8 number of supported LUNs
+CFG_SCSI_MAX_SCSI_ID 7 maximum SCSI ID (0..6)
+CFG_SCSI_MAX_DEVICE CFG_SCSI_MAX_SCSI_ID * CFG_SCSI_MAX_LUN
+ maximum of Target devices (multiple LUN support
+ for boot)
+
+ISO (CD-Boot) partition support (Experimental)
+----------------------------------------------
+CONFIG_ISO_PARTITION CD-boot support
+
+RTC
+----
+CONFIG_RTC_MC146818 MC146818 RTC support
+
+Keyboard:
+---------
+CONFIG_ISA_KEYBOARD Standard (PC-Style) Keyboard support
+
+Video:
+------
+CONFIG_VIDEO_CT69000 Enable Chips & Technologies 69000 Video chip
+ CONFIG_VIDEO must be defined also
+
+External peripheral base address:
+---------------------------------
+CFG_ISA_IO_BASE_ADDRESS address of all ISA-bus related parts
+ _must_ be defined for ISA-bus parts
+
+Identify:
+---------
+CONFIG_IDENT_STRING added to the U_BOOT_VERSION String
+
+
+I2C stuff:
+----------
+CFG_EEPROM_PAGE_WRITE_ENABLE enables page write of the I2C EEPROM
+ CFG_EEPROM_PAGE_WRITE_BITS _must_ be
+ defined.
+
+
+Environment / Console:
+----------------------
+
+CFG_CONSOLE_IS_IN_ENV if defined, stdin, stdout and stderr used from
+ the values stored in the evironment.
+
+CFG_CONSOLE_OVERWRITE_ROUTINE if defined, console_overwrite() decides if the
+ values stored in the environment or the standard
+ serial in/out put should be assigned to the console.
+
+CFG_CONSOLE_ENV_OVERWRITE if defined, the start-up console switching
+ are stored in the environment.
+
+PIP405 specific:
+----------------
+CONFIG_PORT_ADDR address used to read boot configuration
+MULTI_PURPOSE_SOCKET_ADDR address of the multi purpose socked
+SDRAM_EEPROM_WRITE_ADDRESS addresses of the serial presence detect
+SDRAM_EEPROM_READ_ADDRESS EEPROM on the SDRAM module.
+
+
+Changes:
+========
+
+Added Devices:
+==============
+
+Floppy support:
+---------------
+Support of a standard floppy disk controller at address CFG_ISA_IO_BASE_ADDRESS
++ 0x3F0. Enabled with define CFG_CMD_FDC. Reads a unformated floppy disk with a
+image header (see: mkimage). No interrupts and no DMA are used for this.
+Added files:
+- common/cmd_fdc.c
+- include/cmd_fdc.h
+
+SCSI support:
+-------------
+Support for Symbios SYM53C810A chip. Implemented as follows:
+- without disconnect
+- only asynchrounous
+- multiple LUN support (caution, needs a lot of RAM. define CFG_SCSI_MAX_LUN 1 to
+ save RAM)
+- multiple SCSI ID support
+- no write support
+- analyses the MAC, DOS and ISO pratition similar to the IDE support
+- allows booting from SCSI devices similar to the IDE support.
+The device numbers are not assigned like they are within the IDE support. The first
+device found will get the number 0, the next 1 etc. If all SCSI IDs (0..6) and all
+LUNs (8) are enabled, 56 boot devices are possible. This uses a lot of RAM since the
+device descriptors are not yet dynamically allocated. 56 boot devices are overkill
+anyway. Please refer to the section "Todo" chapter "block device support enhancement".
+The SYM53C810A uses 1 Interrupt and must be able of mastering the PCI bus.
+Added files:
+- common/cmd_scsi.c
+- common/board.c
+- include/cmd_scsi.h
+- include/scsi.h
+- board/pip405/sym53c8xx.c
+- board/pip405/sym53c8xx_defs.h
+
+ATAPI support (IDE changes):
+----------------------------
+Added ATAPI support (with CONFIG_ATAPI) in the file cmd_ide.c.
+To support a hardreset, when the IDE reset pin is not connected to the
+CFG_PC_IDE_RESET pin, the switch CONFIG_IDE_RESET_ROUTINE has been added. When
+this switch is enabled the routine void ide_set_reset(int idereset) must be
+within the board specific files.
+Only read from ATAPI devices are supported.
+Found out that the function trim_trail cuts off the last character if the whole
+string is filled. Added function cpy_ident instead, which trims also leading
+spaces and copies the string in the buffer.
+Changed files:
+- common/cmd_ide.c
+- include/ata.h
+
+ISO partition support:
+----------------------
+Added CD boot support for El-Torito bootable ISO CDs. The bootfile image must contain
+the U-Boot image header. Since CDs do not have "partitions", the boot partition is 0.
+The bootcatalog feature has not been tested so far. CD Boot is supported for ATAPI
+("diskboot") and SCSI ("scsiboot") devices.
+Added files:
+- disk/iso_part.c
+- disk/iso_part.h
+
+Block device changes:
+---------------------
+To allow the use of dos_part.c, mac_part.c and iso_part.c, the parameter
+block_dev_desc will be used when accessing the functions in these files. The block
+device descriptor (block_dev_desc) contains a pointer to the read routine of the
+device, which will be used to read blocks from the device.
+Renamed function ide_print to dev_print and moved it to the file disk/part.c to use
+it for IDE ATAPI and SCSI devices.
+Please refer to the section "Todo" chapter "block device support enhancement".
+Added files:
+- include/part.h
+changed files:
+- disk/dos_part.c
+- disk/dos_part.h
+- disk/mac_part.c
+- disk/mac_part.h
+- disk/part.c
+- common/cmd_ide.c
+- include/u-boot.h
+
+
+MC146818 RTC support:
+---------------------
+Added support for MC146818 RTC with defining CONFIG_RTC_MC146818. The ISA bus IO
+base address must be defined with CFG_ISA_IO_BASE_ADDRESS.
+Added files:
+- rtc/mc146818.c
+
+Standard ISA bus Keyboard support:
+----------------------------------
+Added support for the standard PC kyeboard controller. For the PIP405 the superIO
+controller must be set up previously. The keyboard uses the standard ISA IRQ, so
+the ISA PIC must also be set up.
+Added files:
+- board/pip405/kbd.c
+- board/pip405/kbd.h
+- board/pip405/pip405_isa.c
+- board/pip405/pip405_isa.h
+
+Chips and Technologie 69000 VGA controller support:
+---------------------------------------------------
+Added support for the CT69000 VGA controller.
+Added files:
+- board/pip405/video.c
+- board/pip405/video.h
+- board/pip405/vga_table.h
+
+
+Changed Items:
+==============
+
+Identify:
+---------
+Added the config variable CONFIG_IDENT_STRING which will be added to the
+"U_BOOT_VERSION __TIME__ DATE___ " String, to allows to identify intermidiate
+and custom versions.
+Changed files:
+- cpu/ppc4xx/start.s
+
+Firmware Image:
+---------------
+Added IH_OS_U_BOOT and IH_TYPE_FIRMWARE to the image definitions to allows the
+U-Boot update with prior CRC check.
+Changed files:
+- include/image.h
+- tools/mkimage.c
+- common/cmd_bootm.c
+
+Correct PCI Frequency for PPC405:
+---------------------------------
+Added function (in cpu/ppc4xx/speed.c) to get the PCI frequency for PPC405 CPU.
+The PCI Frequency will now be set correct in the board description in common/board.c.
+(was set to the busfreq before).
+Changed files:
+- cpu/ppc4xx/speed.c
+- common/board.c
+
+I2C Stuff:
+----------
+Added defined(CONFIG_PIP405) at several points in common/cmd_i2c.c.
+Added 16bit read/write support for I2C (PPC405), and page write to
+I2C EEPROM if defined CFG_EEPROM_PAGE_WRITE_ENABLE.
+Changed files:
+- cpu/ppc4xx/i2c.c
+- common/cmd_i2c.c
+
+Environment / Console:
+----------------------
+Although in README.console described, the U-Boot has not assinged the values
+found in the environment to the console. Corrected this behavior, but only if
+CFG_CONSOLE_IS_IN_ENV is defined.
+If CFG_CONSOLE_OVERWRITE_ROUTINE is defined, console_overwrite() decides if the
+values stored in the environment or the standard serial in/output should be
+assigned to the console. This is useful if the environment values are not correct.
+If CFG_CONSOLE_ENV_OVERWRITE is defined the devices assigned to the console at
+start-up time will be written to the environment. This means that if the
+environment values are overwritten by the overwrite_console() routine, they will be
+stored in the environment.
+Changed files:
+- common/console.c
+
+Correct bootdelay intepretation:
+--------------------------------
+Changed bootdelay read from the environment from simple_strtoul (unsigned) to
+simple_strtol (signed), to be able to get a bootdelay of -1.
+Changed files:
+- common/main.c
+
+Todo:
+=====
+
+Block device support enhancement:
+---------------------------------
+Consider to unify the block device handling. Instead of using diskboot for IDE,
+scsiboot for SCSI and fdcboot for floppy disks, it would make sense to use only
+one command ("devboot" ???) with a parameter of the desired device ("hda1", "sda1",
+"fd0" ???) to boot from. The other ide commands can be handled in the same way
+("dev hda read.." instead of "ide read.." or "dev sda read.." instead of
+"scsi read..."). Todo this, a common way of assign a block device to its name
+(first found ide device = hda, second found hdb etc., or hda is device 0 on bus 0,
+hdb is device 1 on bus 0 etc.) as well as the names (hdx for ide, sdx for scsi, fx for
+floppy ???) must be defined.
+Maybe there are better ideas to do this.
+
+Console assingment:
+-------------------
+Consider to initialize and assign the console stdin, stdout and stderr as soon as
+possible to see the boot messages also on an other console than serial.
+
+
+Todo for PIP405:
+================
+
+LCD support for VGA:
+--------------------
+Add LCD support for the CT69000
+
+Default environment:
+--------------------
+Consider to write a default environment to the OTP part of the EEPROM and use it
+if the normal environment is not valid. Useful for serial# and ethaddr values.
+
+Watchdog:
+---------
+Implement Watchdog.
+
+Files clean-up:
+---------------
+Following files needs to be cleaned up:
+- cmd_pip405.c
+- flash.c
+- pci_pip405.c
+- pip405.c
+- pip405_isa.c
+Consider to split up the files in their functions.

+
+1.1. Board, BDM settings
+ Install board, BDM, connect each other
+
+1.2. Save Register value
+ Boot with board-on monitor program and save the
+ register values with BDM.
+
+1.3. Configure flash programmer
+ Check flash memory area in the memory map.
+ 0xFFC00000 - 0xFFFFFFFF
+
+ Boot monitor program is at
+ 0xFFF00000
+
+ You can program on-board flash memory with VisionClick
+ flash programmer. Set the target flash device as:
+
+ 29DL800B
+
+ (?) The flash memory device in the board *is* 29LV800B,
+ but I cannot program it with '29LV800B' option.
+ (in VisionClick flash programming tools)
+ I don't know why...
+
+1.4. Save boot monitor program *IMPORTANT*
+ Upload boot monitor program from board to file.
+ boot monitor program starts at 0xFFF00000
+
+1.5. Test flash memory programming
+ Try to erase boot program in the flash memory,
+ and re-write them.
+ *WARNING* YOU MUST SAVE BOOT PROGRAM TO FILE
+ BEFORE ERASING FLASH

+
+2.1. Download U-Boot tarball at
+ ftp://ftp.denx.de
+ (The latest version is ppcboot-0.8.1.tar.bz2)
+
+ To extract the archive use the following syntax :
+ > bzip2 -cd ppcboot-0.8.1.tar.bz2 | tar xf -
+
+2.2. Add the following lines in '.profile'
+ export PATH=$PATH:/opt/hardhat/devkit/ppc/8xx/bin
+
+2.3. Make board specific config, for example:
+ > cd ppcboot-0.8.1
+ > make TQM860L_config
+
+ Now we can build ppcboot bin files.
+ After make all, you must see these files in your
+ ppcboot root directory.
+
+ ppcboot
+ ppcboot.bin
+ ppcboot.srec
+ ppcboot.map
+
+2.4. Make your own board directory into the
+ ppcboot-0.8.1/board
+ and make your board-specific files here.
+
+ For exmanple, tqm8xx files are composed of
+ .depend : Nothing
+ Makefile : To make config file
+ config.mk : Sets base address
+ flash.c : Flash memory control files
+ ppcboot.lds : linker(ld) script? (I don't know this yet)
+ tqm8xx.c : DRAM control and board check routines
+
+ And, add your board config lines in the
+ ppcboot-0.8.1/Makefile
+
+ Finally, add config_(your board).h file in the
+ ppcboot-0.8.1/include/
+
+ I've made board/rpxlite directory, and just copied
+ tqm8xx settings for now.
+
+ Rebuild ppcboot for rpxlite board:
+ > make rpxlite_config
+ > make
+

+PART 1)
+ DIP Switch Settings:
+
+Sandpoint X3 8240 processor board DIP switch settings, with
+U-Boot to be installed in the flash memory of the CPU card:
+
+Motorola Sandpoint X3 Motherboard:
+SW1.1: on SW1.2: on SW1.3: on SW1.4: on
+SW1.5: on SW1.6: on SW1.7: on SW1.8: on

+
+
+PART 2)
+ Connect the BDI2000 Cable to the Sandpoint/Unity 8240:
+
+BDM Pin 1 on the Unity 8240 processor board is towards the
+PCI PMC connectors, or away from the socketed SDRAM, i.e.:
+
+ ====================
+ | ---------------- |
+ | | SDRAM | |

+ | ~ 1 ++++++ |
+ | |
+ | |
+ | |
+ | PMC conn ====== |
+ | ===== ====== |
+ | |
+ ====================
+
+
+PART 3)
+ Setting up the BDI2000, and preparing for TCP/IP network comms:
+
+Connect the BDI2000 to the PC using the supplied serial cable.
+Download the BDI2000 software and install it using setup.exe.
+
+[Note: of course you can also use the Linux command line tool
+"bdisetup" to configure your BDI2000 - the sources are included on
+the floppy disk that comes with your BDI2000. Just in case you don't
+have any Windows PC's - like me :-) -- wd ]
+
+Power up the BDI2000; then follow directions to assign the IP
+address and related network information. Note that U-Boot
+will be loaded to the Sandpoint via tftp. You need to either
+use the Abatron-provided tftp application or provide a tftp
+server (e.g. Linux/Solaris/*BSD) somewhere on your network.
+Once the IP address etc are assigned via the RS232 port,
+further communication with the BDI2000 will happen via the
+ethernet connection.
+
+PART 4)
+ Making a TCP/IP network connection to the Abatron BDI2000:
+
+Telnet to the Abatron BDI2000. Assuming that all of the
+networking info was loaded via RS232 correctly, you will see
+the following (scrolling):
+
+- TARGET: waiting for target Vcc
+- TARGET: waiting for target Vcc
+
+
+PART 5)
+ Power up the target Sandpoint:
+If the BDM connections are correct, the following will now appear:

+
+BDI>prog 0xFFF00000 u-boot.bin bin
+ Programming u-boot.bin , please wait ....
+ Programming flash passed
+
+
+PART 8)
+ Connect PC to Sandpoint:
+Using a crossover serial cable, attach the PC serial port to the
+Sandpoint's COM1. Set communications parameters to 8N1 / 9600 baud.
+
+
+PART 9)
+ Reset the Unity and begin U-Boot execution:
+
+BDI>reset

+- TARGET: Target PVR is 0x00810101
+- TARGET: reseting target passed
+- TARGET: processing target init list ....

+/* Ok, so anyone who knows the jffs2 code will probably want to get a papar
+ * bag to throw up into before reading this code. I looked through the jffs2
+ * code, the caching scheme is very elegant. I tried to keep the version
+ * for a bootloader as small and simple as possible. Instead of worring about
+ * unneccesary data copies, node scans, etc, I just optimized for the known
+ * common case, a kernel, which looks like:
+ * (1) most pages are 4096 bytes
+ * (2) version numbers are somewhat sorted in acsending order
+ * (3) multiple compressed blocks making up one page is uncommon
+ *
+ * So I create a linked list of decending version numbers (insertions at the
+ * head), and then for each page, walk down the list, until a matching page
+ * with 4096 bytes is found, and then decompress the watching pages in
+ * reverse order.

+Hymod Board Database

+
+This stuff is a set of PHP/MySQL scripts to implement a custom board
+database. It will need *extensive* hacking to modify it to keep the
+information about your custom boards that you want, however it is a good
+starting point.
+
+How it is used:
+
+ 1. a board has gone through all the hardware testing etc and is
+ ready to have the flash programmed for the first time - first you
+ go to a web page and fill in information about the board in a form
+ to register it in a database
+
+ 2. the web stuff allocates a (unique) serial number and (optionally)
+ a (locally administered) ethernet address and stores the information
+ in a database using the serial number as the key (can do whole
+ batches of boards in one go and/or use a previously registered board
+ as defaults for the new board(s))
+
+ 3. it then creates a file in the tftp area of a server somewhere
+ containing the board information in a simple text format (one
+ per serial number)
+
+ 4. all hymod boards have an i2c eeprom, and when U-Boot sees that
+ the eeprom is unitialised, it prompts for a serial number and
+ ethernet address (if not set), then transfers the file created
+ in step 3 from the server and initialises the eeprom from its
+ contents
+
+What this means is you can't boot the board until you have allocated a serial
+number, but you don't have to type it all twice - you do it once on the web
+and the board then finds the info it needs to initialise its eeprom. The
+other side of the coin is the reading of the eeprom and how it gets passed
+to Linux (or another O/S).
+
+To see how this is all done for the hymod boards look at the code in the
+"board/hymod" directory and in the file "include/asm/hymod.h". Hymod boards
+can have a mezzanine card which also have an eeprom that needs allocating,
+the same process is used for these as well - just a different i2c address.
+
+Other forms provide the following functions:
+
+ - browsing the board database
+ - editing board information (one at a time)
+ - maintaining/browsing a (simple) per board event log
+
+You will need: MySQL (I use version 3.23.7-alpha), PHP4 (with MySQL
+support enabled) and a web server (I use Apache 1.3.x).
+
+I originally started by using phpMyBuilder (http://kyber.dk/phpMyBuilder)
+but it soon got far more complicated than that could handle (but I left
+the copyright messages in there anyway). Most of the code resides in the
+common defs.php file, which shouldn't need much alteration - all the work
+will be in shaping the front-end php files to your liking.
+
+Here's a quick summary of what needs doing to use it for your boards:
+
+1. get phpMyAdmin (http://phpwizard.net/projects/phpMyAdmin/) - it's an
+ invaluable tool for this sort of stuff (this step is optional of course)
+
+2. edit "bddb.css" to your taste, if you could be bothered - I have no
+ idea what is in there or what it does - I copied it from somewhere else
+ ("user.css" from the phpMyEdit (http://phpmyedit.sourcerforge.net) package,
+ I think) - I figure one day I'll see what sort of things I can change
+ in there.
+
+3. create a mysql database - call it whatever you like
+
+4. edit "create_tables.sql" and modify the "boards" table schema to
+ reflect the information you want to keep about your boards. It may or
+ may not be easier to do this and the next step in phpMyAdmin. Check out
+ the MySQL documentation at http://www.mysql.com/doc/ in particular the
+ column types at http://www.mysql.com/doc/C/o/Column_types.html - Note
+ there is only support for a few data types:
+
+ int - presented as an html text input
+ char/text - presented as an html text input
+ date - presented as an html text input
+ enum - presented as an html radio input
+
+ I also have what I call "enum_multi" which is a set of enums with the
+ same name, but suffixed with a number e.g. fred0, fred1, fred2. These
+ are presented as a number of html select's with a single label "fred"
+ this is useful for board characteristics that have multiple items of
+ the same type e.g. multiple banks of sdram.
+
+5. use the "create_tables.sql" file to create the "boards" table in the
+ database e.g. mysql dbname < create_tables.sql
+
+6. create a user and password for the web server to log into the MySQL
+ database with; give this user select, insert and update privileges
+ to the database created in 3 (and delete, if you want the "delete"
+ functions in the edit forms to work- I have this turned off). phpMyAdmin
+ helps in this step.
+
+7. edit "config.php" and set the variables: $mysql_user, $mysql_pw, $mysql_db,
+ $bddb_cfgdir and $bddb_label - keep the contents of this file secret - it
+ contains the web servers username and password (the three $mysql_* vars
+ are set from the previous step)
+
+8. edit "defs.php" and a. adjust the various enum value arrays and b. edit
+ the function "pg_foot()" to remove my email address :-)
+
+9. do major hacking on the following files: browse.php, doedit.php, donew.php,
+ edit.php and new.php to reflect your database schema - fortunately the
+ hacking is fairly straight-forward, but it is boring and time-consuming.
+
+These notes were written rather hastily - if you find any obvious problems
+please let me know.
