+
CONFIG_SPL_PAD_TO
- Linker address to which the SPL should be padded before
- appending the SPL payload.
+ Image offset to which the SPL should be padded before appending
+ the SPL payload. By default, this is defined as
+ CONFIG_SPL_MAX_SIZE, or 0 if CONFIG_SPL_MAX_SIZE is undefined.
+ CONFIG_SPL_PAD_TO must be either 0, meaning to append the SPL

use an arch-specific makefile fragment instead, for
example if more than one image needs to be produced.
+ CONFIG_FIT_SPL_PRINT

--------------
digits and dots. Recommended value: 45 (9..1) for 80
column displays, 15 (3..1) for 40 column displays.

+ If defined, the content of the flash (destination) is compared
+ against the source after the write operation. An error message
+ will be printed when the contents are not identical.
+ Please note that this option is useless in nearly all cases,
+ since such flash programming errors usually are detected earlier
+ while unprotecting/erasing/programming. Please only enable
+ this option if you really know what you are doing.
+
- CONFIG_SYS_RX_ETH_BUFFER:
Defines the number of Ethernet receive buffers. On some
Ethernet controllers it is recommended to set this value
offset _bss_start_ofs from CONFIG_SYS_TEXT_BASE, rather than
directly. You should not need to touch this setting.
+- CONFIG_OMAP_PLATFORM_RESET_TIME_MAX_USEC (OMAP only)
+ This is set by OMAP boards for the max time that reset should
+ be asserted. See doc/README.omap-reset-time for details on how
+ the value can be calulated on a given board.
The following definitions that deal with the placement and management
of environment data (variable area); in general, we support the
environment. If redundant environment is used, it will be copied to
CONFIG_NAND_ENV_DST + CONFIG_ENV_SIZE.
+- CONFIG_ENV_IS_IN_UBI:
+
+ Define this if you have an UBI volume that you want to use for the
+ environment. This has the benefit of wear-leveling the environment
+ accesses, which is important on NAND.
+
+ - CONFIG_ENV_UBI_PART:
+
+ Define this to a string that is the mtd partition containing the UBI.
+
+ - CONFIG_ENV_UBI_VOLUME:
+
+ Define this to the name of the volume that you want to store the
+ environment in.
+
+ - CONFIG_ENV_UBI_VOLUME_REDUND:
+
+ Define this to the name of another volume to store a second copy of
+ the environment in. This will enable redundant environments in UBI.
+ It is assumed that both volumes are in the same MTD partition.
+
+ - 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
- CONFIG_SYS_SRIOn_MEM_SIZE:
Size of SRIO port 'n' memory region
-- CONFIG_SYS_NDFC_16
- Defined to tell the NDFC that the NAND chip is using a
- 16 bit bus.
+- CONFIG_SYS_NAND_BUSWIDTH_16BIT
+ Defined to tell the NAND controller that the NAND chip is using
+ a 16 bit bus.
+ Not all NAND drivers use this symbol.
+ Example of drivers that use it:
+ - drivers/mtd/nand/ndfc.c
+ - drivers/mtd/nand/mxc_nand.c
- CONFIG_SYS_NDFC_EBC0_CFG
Sets the EBC0_CFG register for the NDFC. If not defined
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>".
