Flashing U-Boot
--------------------------------
-There are two options: the original bootloader in NAND can be replaced with
-u-boot, or u-boot can be stored on the NOR flash without erasing
-the delivered bootloader.
+U-boot should be stored on the NOR flash.
+
The boot storage can be select using the switches on the personality board
(SW1-SW2) and on the DEBUG board (SW4-SW10).
-The second option is to be preferred if you have not a JTAG debugger.
If something goes wrong flashing the bootloader, it is always possible to
recover the board booting from the other device.
-Replacing the bootloader on the NAND
---------------------------------------
-To replace RedBoot with U-Boot, the easy way is to do this in linux.
-Start the kernel with the suggested options. Make sure to have set the
-mtdparts exactly as described, because this matches the layout on the
-mx35pdk.
-
-You should see in your boot log the following entries for the NAND
-flash:
-
-5 cmdlinepart partitions found on MTD device mxc_nand
-Creating 5 MTD partitions on "mxc_nand":
-0x000000000000-0x000000100000 : "boot"
-0x000000100000-0x000000600000 : "linux"
-0x000000600000-0x000006600000 : "root"
-0x000006600000-0x000006e00000 : "cfg"
-0x000006e00000-0x000080000000 : "user"
-
-You can use the utilities flash_eraseall and nandwrite to put
-u-boot on the NAND. The bootloader is marked as "boot", and 1MB is
-reserved. If everything is correct, this partition is accessed as
-/dev/mtd4. However, check if it is correct with "cat /proc/mtd" and
-get the device node from the partition name:
-
-$ cat /proc/mtd | grep boot
-
-I suggest you try the utilities on a different partition to be sure
-if everything works correctly. If not, and you remove RedBoot, you have to
-reinstall it using the ATK tool as suggested by Freescale, or using a
-JTAG debugger.
-
-I report the versions of the utilities I used (they are provided with ELDK):
-
--bash-3.2# nandwrite --version
-nandwrite $Revision: 1.32 $
-
-flash_eraseall --version
-flash_eraseall $Revision: 1.22 $
-
-nandwrite reports a warning if the file to be saved is not sector aligned.
-This should have no consequences, but I preferred to pad u-boot.bin
-to get no problem at all.
-$ dd if=/dev/zero of=zeros bs=1 count=74800
-$ cat u-boot.bin zeros > u-boot-padded.bin
-
-To erase the partition:
-$ flash_eraseall /dev/mtd4
-
-Writing u-boot:
-
-$ nandwrite /dev/mtd4 u-boot-padded.bin
-
-Now U-Boot is stored on the booting partition.
-
-To boot from NAND, you have to select the switches as follows:
-
-Personality board
- SW2 1, 4, 5 on
- 2, 3, 6, 7, 8 off
- SW1 all off
-
-Debug Board:
- SW5 0
- SW6 0
- SW7 0
- SW8 1
- SW9 1
- SW10 0
-
-
Saving U-Boot in the NOR flash
---------------------------------
-The procedure to save in the NOR flash is quite the same as to write into the NAND.
-
Check the partition for boot in the NOR flash. Setting the mtdparts as reported,
the boot partition should be /dev/mtd0.

+This patch series adds support for ext4 ls,load and write features in uboot
+Journaling is supported for write feature.
+
+To Enable ext2 ls and load commands, modify the board specific config file with
+#define CONFIG_CMD_EXT2
+
+To Enable ext4 ls and load commands, modify the board specific config file with
+#define CONFIG_CMD_EXT4
+
+To enable ext4 write command, modify the board specific config file with
+#define CONFIG_CMD_EXT4
+#define CONFIG_CMD_EXT4_WRITE
+
+Steps to test:
+
+1. After applying the patch, ext4 specific commands can be seen
+ in the boot loader prompt using
+ UBOOT #help
+
+ ext4load- load binary file from a Ext4 file system
+ ext4ls - list files in a directory (default /)
+ ext4write- create a file in ext4 formatted partition
+
+2. To list the files in ext4 formatted partition, execute
+ ext4ls <interface> <dev[:part]> [directory]
+ For example:
+ UBOOT #ext4ls mmc 0:5 /usr/lib
+
+3. To read and load a file from an ext4 formatted partition to RAM, execute
+ ext4load <interface> <dev[:part]> [addr] [filename] [bytes]
+ For example:
+ UBOOT #ext4load mmc 2:2 0x30007fc0 uImage
+
+4. To write a file to a ext4 formatted partition.
+ a) First load a file to RAM at a particular address for example 0x30007fc0.
+ Now execute ext4write command
+ ext4write <interface> <dev[:part]> [filename] [Address] [sizebytes]
+ For example:
+ UBOOT #ext4write mmc 2:2 /boot/uImage 0x30007fc0 6183120
+ (here 6183120 is the size of the file to be written)
+ Note: Absolute path is required for the file to be written

+Freescale PBL(pre-boot loader) Boot Image generation using mkimage
+------------------------------------------------------------------
+
+The CoreNet SoC's can boot directly from eSPI FLASH, SD/MMC and
+NAND, etc. These SoCs use PBL to load RCW and/or pre-initialization
+instructions. For more details refer section 5 Pre-boot loader
+specifications of reference manual P3041RM/P4080RM/P5020RM at link:
+http://www.freescale.com/webapp/search/Serp.jsp?Reference+Manuals
+
+Building PBL Boot Image and boot steps
+--------------------------------------
+
+1. Building PBL Boot Image.
+ The default Image is u-boot.pbl.
+
+ For eSPI boot(available on P3041/P4080/P5020):
+ To build the eSPI boot image:
+ make <board_name>_SPIFLASH_config
+ make u-boot.pbl
+
+ For SD boot(available on P3041/P4080/P5020):
+ To build the SD boot image:
+ make <board_name>_SDCARD_config
+ make u-boot.pbl
+
+ For Nand boot(available on P3041/P5020):
+ To build the NAND boot image:
+ make <board_name>_NAND_config
+ make u-boot.pbl
+
+
+2. pblimage support available with mkimage utility will generate Freescale PBL
+boot image that can be flashed on the board eSPI flash, SD/MMC and NAND.
+Following steps describe it in detail.
+
+ 1). Boot from eSPI flash
+ Write u-boot.pbl to eSPI flash from offset 0x0.
+ for ex in u-boot:
+ =>tftp 100000 u-boot.pbl
+ =>sf probe 0
+ =>sf erase 0 100000
+ =>sf write 100000 0 $filesize
+ Change SW1[1:5] = off off on off on.
+
+ 2). Boot from SD/MMC
+ Write u-boot.pbl to SD/MMC from offset 0x1000.
+ for ex in u-boot:
+ =>tftp 100000 u-boot.pbl
+ =>mmcinfo
+ =>mmc write 100000 8 441
+ Change SW1[1:5] = off off on on off.
+
+ 3). Boot from Nand
+ Write u-boot.pbl to Nand from offset 0x0.
+ for ex in u-boot:
+ =>tftp 100000 u-boot.pbl
+ =>nand info
+ =>nand erase 0 100000
+ =>nand write 100000 0 $filesize
+ Change SW1[1:5] = off on off off on
+ Change SW7[1:4] = on off off on
+
+Board specific configuration file specifications:
+------------------------------------------------
+1. Configuration files rcw.cfg and pbi.cfg must present in the
+board/freescale/corenet_ds/, rcw.cfg is for RCW, pbi.cfg is for
+PBI instructions. File name must not be changed since they are used
+in Makefile.
+2. These files can have empty lines and lines starting with "#" as first

-SRIO Boot on Corenet Platforms
-------------------------------
-
-For some PowerPC processors with SRIO interface, boot location can be configured
-to SRIO by RCW. The processor booting from SRIO can do without flash for u-boot
-image, ucode and ENV. All the images can be fetched from another processor's
-memory space by SRIO link connected between them.
-
-This document describes the processes based on an example implemented on P4080DS
-platforms and a RCW example with boot from SRIO configuration.
-
-Environment of the SRIO boot:
- a) Master and slave can be SOCs in one board or SOCs in separate boards.
- b) They are connected with SRIO links, whether 1x or 4x, and directly or
- through switch system.
- c) Only Master has NorFlash for booting, and all the Master's and Slave's
- U-Boot images, UCodes will be stored in this flash.
- d) Slave has its own EEPROM for RCW and PBI.
- e) Slave's RCW should configure the SerDes for SRIO boot port, set the boot
- location to SRIO, and holdoff all the cores if needed.

- ---------- ----------- -----------
-
-The example based on P4080DS platform:
- Two P4080DS platforms can be used to implement the boot from SRIO. Their SRIO
- ports 0 will be connected directly and will be used for the boot from SRIO.
-
- 1. Slave's RCW example for boot from SRIO port 0 and core 0 not in holdoff.

-
- 3. Sequence in Step by Step.
- a) Update RCW for slave with boot from SRIO port 0 configuration.
- b) Program slave's U-Boot image, UCode, and ENV parameters into master's
- NorFlash.
- c) Start up master and it will boot up normally from its NorFlash.
- Then, it will finish necessary configurations for slave's boot from
- SRIO port 0.
- d) Master will set inbound SRIO windows covered slave's U-Boot image stored
- in master's NorFlash.
- e) Master will set an inbound SRIO window covered slave's UCode stored in
- master's NorFlash.
- f) Master will set an inbound SRIO window covered slave's ENV stored in
- master's NorFlash.
- g) If need to release slave's core, master will set outbound SRIO windows
- in order to configure slave's registers for the core's releasing.
- h) If all cores of slave in holdoff, slave should be powered on before all
- the above master's steps, and wait to be released by master. If not all
- cores in holdoff, that means core 0 will start up normally, slave should
- be powered on after all the above master's steps. In the startup phase
- of the slave from SRIO, it will finish some necessary configurations.
- i) Slave will set a specific TLB entry for the boot process.
- j) Slave will set a LAW entry with the TargetID SRIO port 0 for the boot.
- k) Slave will set a specific TLB entry in order to fetch UCode and ENV
- from master.
- l) Slave will set a LAW entry with the TargetID SRIO port 0 for UCode and ENV.
-
-How to use this feature:
- To use this feature, you need to focus three points.
-
- 1. Slave's RCW with SRIO boot configurations, and all cores in holdoff
- configurations if needed.
- Please refer to the examples given above.
-
- 2. U-Boot image's compilation.
- For master, U-Boot image should be generated specifically by
-
- make xxxx_SRIOBOOT_MASTER_config.
-
- For example, master U-Boot image used on P4080DS should be compiled with
-
- make P4080DS_SRIOBOOT_MASTER_config.
-
- For slave, U-Boot image should be generated specifically by
-
- make xxxx_SRIOBOOT_SLAVE_config.
-
- For example, slave U-Boot image used on P4080DS should be compiled with
-
- make P4080DS_SRIOBOOT_SLAVE_config.
-
- 3. Necessary modifications based on a specific environment.
- For a specific environment, the SRIO port for boot, the addresses of the
- slave's U-Boot image, UCode, ENV stored in master's NorFlash, and any other
- configurations can be modified in the file:
- include/configs/corenet_ds.h.

+ Order is: MAX_TRP_TREA, TWB, Max(tCS, tCH, tALS, tALH),
+ TWHR, Max(tCS, tCH, tALS, tALH), TWH, TWP, TRH, TADL
+
+ MAX_TRP_TREA is:
+ non-EDO mode: Max(tRP, tREA) + 6ns
+ EDO mode: tRP timing
+
+The 'reg' property should provide the chip select used by the flash chip.
