+
+ ported i2c driver to the new framework:
+ - drivers/i2c/soft_i2c.c:
+ - activate first bus with CONFIG_SYS_I2C_SOFT define

+
+ additional defines:
+
+ CONFIG_SYS_NUM_I2C_BUSES
+ Hold the number of i2c busses you want to use. If you
+ don't use/have i2c muxes on your i2c bus, this
+ is equal to CONFIG_SYS_NUM_I2C_ADAPTERS, and you can

+
+ CONFIG_SYS_I2C_DIRECT_BUS

+
+ If you do not have i2c muxes on your board, omit this define.
+
+- Legacy I2C Support: CONFIG_HARD_I2C
+
+ NOTE: It is intended to move drivers to CONFIG_SYS_I2C which
+ provides the following compelling advantages:
+
+ - more than one i2c adapter is usable
+ - approved multibus support
+ - better i2c mux support
+
+ ** Please consider updating your I2C driver now. **
+
+ These enable legacy I2C serial bus commands. Defining
+ CONFIG_HARD_I2C will include the appropriate I2C driver
+ for the selected CPU.
This will allow you to use i2c commands at the u-boot
command line (as long as you set CONFIG_CMD_I2C in
CONFIG_HARD_I2C selects a hardware I2C controller.
- CONFIG_SOFT_I2C configures u-boot to use a software (aka
- bit-banging) driver instead of CPM or similar hardware
- support for I2C.
-
There are several other quantities that must also be
- defined when you define CONFIG_HARD_I2C or CONFIG_SOFT_I2C.
+ defined when you define CONFIG_HARD_I2C.
In both cases you will need to define CONFIG_SYS_I2C_SPEED
to be the frequency (in Hz) at which you wish your i2c bus
That's all that's required for CONFIG_HARD_I2C.
- If you use the software i2c interface (CONFIG_SOFT_I2C)
+ If you use the software i2c interface (CONFIG_SYS_I2C_SOFT)
then the following macros need to be defined (examples are
from include/configs/lwmon.h):
I2C_READ
- Code that returns TRUE if the I2C data line is high,
- FALSE if it is low.
+ Code that returns true if the I2C data line is high,
+ false if it is low.
eg: #define I2C_READ ((immr->im_cpm.cp_pbdat & PB_SDA) != 0)
I2C_SDA(bit)
- If <bit> is TRUE, sets the I2C data line high. If it
- is FALSE, it clears it (low).
+ If <bit> is true, sets the I2C data line high. If it
+ is false, it clears it (low).
eg: #define I2C_SDA(bit) \
if(bit) immr->im_cpm.cp_pbdat |= PB_SDA; \
I2C_SCL(bit)
- If <bit> is TRUE, sets the I2C clock line high. If it
- is FALSE, it clears it (low).
+ If <bit> is true, sets the I2C clock line high. If it
+ is false, it clears it (low).
eg: #define I2C_SCL(bit) \
if(bit) immr->im_cpm.cp_pbdat |= PB_SCL; \
If not defined, then U-Boot uses predefined value for
specified DTT device.
- CONFIG_FSL_I2C
-
- Define this option if you want to use Freescale's I2C driver in
- drivers/i2c/fsl_i2c.c.
-
- CONFIG_I2C_MUX
-
- Define this option if you have I2C devices reached over 1 .. n
- I2C Muxes like the pca9544a. This option addes a new I2C
- Command "i2c bus [muxtype:muxaddr:muxchannel]" which adds a
- new I2C Bus to the existing I2C Busses. If you select the
- new Bus with "i2c dev", u-bbot sends first the commandos for
- the muxes to activate this new "bus".
-
- CONFIG_I2C_MULTI_BUS must be also defined, to use this
- feature!
-
- Example:
- Adding a new I2C Bus reached over 2 pca9544a muxes
- The First mux with address 70 and channel 6
- The Second mux with address 71 and channel 4
-
- => i2c bus pca9544a:70:6:pca9544a:71:4
-
- Use the "i2c bus" command without parameter, to get a list
- of I2C Busses with muxes:
-
- => i2c bus
- Busses reached over muxes:
- Bus ID: 2
- reached over Mux(es):
- pca9544a@70 ch: 4
- Bus ID: 3
- reached over Mux(es):
- pca9544a@70 ch: 6
- pca9544a@71 ch: 4
- =>
-
- If you now switch to the new I2C Bus 3 with "i2c dev 3"
- u-boot first sends the command to the mux@70 to enable
- channel 6, and then the command to the mux@71 to enable
- the channel 4.
-
- After that, you can use the "normal" i2c commands as
- usual to communicate with your I2C devices behind
- the 2 muxes.
-
- This option is actually implemented for the bitbanging
- algorithm in common/soft_i2c.c and for the Hardware I2C
- Bus on the MPC8260. But it should be not so difficult
- to add this option to other architectures.
-
CONFIG_SOFT_I2C_READ_REPEATED_START
defining this will force the i2c_read() function in
Define this option to include a destructive SPI flash
test ('sf test').
+ CONFIG_SPI_FLASH_BAR Ban/Extended Addr Reg
+
+ Define this option to use the Bank addr/Extended addr
+ support on SPI flashes which has size > 16Mbytes.
+
- SystemACE Support:
CONFIG_SYSTEMACE
Note: There is also a sha1sum command, which should perhaps
be deprecated in favour of 'hash sha1'.
+- Signing support:
+ CONFIG_RSA
+
+ This enables the RSA algorithm used for FIT image verification
+ in U-Boot. See doc/uImage/signature for more information.
+
+ The signing part is build into mkimage regardless of this
+ option.
+
+
- Show boot progress:
CONFIG_SHOW_BOOT_PROGRESS
most specific compatibility entry of U-Boot's fdt's root node.
The order of entries in the configuration's fdt is ignored.
+ CONFIG_FIT_SIGNATURE
+ This option enables signature verification of FIT uImages,
+ using a hash signed and verified using RSA. See
+ doc/uImage.FIT/signature.txt for more details.
+
- Standalone program support:
CONFIG_STANDALONE_LOAD_ADDR
Adds the MTD partitioning infrastructure from the Linux
kernel. Needed for UBI support.
+- UBI support
+ CONFIG_CMD_UBI
+
+ Adds commands for interacting with MTD partitions formatted
+ with the UBI flash translation layer
+
+ Requires also defining CONFIG_RBTREE
+
+ CONFIG_UBI_SILENCE_MSG
+
+ Make the verbose messages from UBI stop printing. This leaves
+ warnings and errors enabled.
+
+- UBIFS support
+ CONFIG_CMD_UBIFS
+
+ Adds commands for interacting with UBI volumes formatted as
+ UBIFS. UBIFS is read-only in u-boot.
+
+ Requires UBI support as well as CONFIG_LZO
+
+ CONFIG_UBIFS_SILENCE_MSG
+
+ Make the verbose messages from UBIFS stop printing. This leaves
+ warnings and errors enabled.

+ - CONFIG_UBI_SILENCE_MSG
+ - CONFIG_UBIFS_SILENCE_MSG
+
+ You will probably want to define these to avoid a really noisy system
+ when storing the env in UBI.
+
+- CONFIG_ENV_IS_IN_MMC:
+
+ Define this if you have an MMC device which you want to use for the
+ environment.
+
+ - CONFIG_SYS_MMC_ENV_DEV:
+
+ Specifies which MMC device the environment is stored in.
+
+ - CONFIG_SYS_MMC_ENV_PART (optional):
+
+ Specifies which MMC partition the environment is stored in. If not
+ set, defaults to partition 0, the user area. Common values might be
+ 1 (first MMC boot partition), 2 (second MMC boot partition).
+
+ - CONFIG_ENV_OFFSET:
+ - CONFIG_ENV_SIZE:
+
+ These two #defines specify the offset and size of the environment
+ area within the specified MMC device.
+
+ If offset is positive (the usual case), it is treated as relative to
+ the start of the MMC partition. If offset is negative, it is treated
+ as relative to the end of the MMC partition. This can be useful if
+ your board may be fitted with different MMC devices, which have
+ different sizes for the MMC partitions, and you always want the
+ environment placed at the very end of the partition, to leave the
+ maximum possible space before it, to store other data.
+
+ These two values are in units of bytes, but must be aligned to an
+ MMC sector boundary.
+
+ - CONFIG_ENV_OFFSET_REDUND (optional):
+
+ Specifies a second storage area, of CONFIG_ENV_SIZE size, used to
+ hold a redundant copy of the environment data. This provides a
+ valid backup copy in case the other copy is corrupted, e.g. due
+ to a power failure during a "saveenv" operation.
+
+ This value may also be positive or negative; this is handled in the
+ same way as CONFIG_ENV_OFFSET.
+
+ This value is also in units of bytes, but must also be aligned to
+ an MMC sector boundary.
+
+ - CONFIG_ENV_SIZE_REDUND (optional):
+
+ This value need not be set, even when CONFIG_ENV_OFFSET_REDUND is
+ set. If this value is set, it must be set to the same value as
+ CONFIG_ENV_SIZE.
+
- CONFIG_SYS_SPI_INIT_OFFSET
Defines offset to the initial SPI buffer area in DPRAM. The
a second time. Useful for platforms that are pre-booted
by coreboot or similar.
+- CONFIG_PCI_INDIRECT_BRIDGE:
+ Enable support for indirect PCI bridges.
+
- CONFIG_SYS_SRIO:
Chip has SRIO or not
- CONFIG_SRIO2:
Board has SRIO 2 port available
+- CONFIG_SRIO_PCIE_BOOT_MASTER
+ Board can support master function for Boot from SRIO and PCIE
+
- CONFIG_SYS_SRIOn_MEM_VIRT:
Virtual Address of SRIO port 'n' memory region
that is executed before the actual U-Boot. E.g. when
compiling a NAND SPL.
+- CONFIG_SYS_MPC85XX_NO_RESETVEC
+ Only for 85xx systems. If this variable is specified, the section
+ .resetvec is not kept and the section .bootpg is placed in the
+ previous 4k of the .text section.
+
- CONFIG_ARCH_MAP_SYSMEM
Generally U-Boot (and in particular the md command) uses
effective address. It is therefore not necessary to regard
using the "bootz" command. The syntax of "bootz" command is the same
as the syntax of "bootm" command.
-Note, defining the CONFIG_SUPPORT_INITRD_RAW allows user to supply
+Note, defining the CONFIG_SUPPORT_RAW_INITRD allows user to supply
kernel with raw initrd images. The syntax is slightly different, the
address of the initrd must be augmented by it's size, in the following
format: "<initrd addres>:<initrd size>".
