Summary:
========
- Board Type: Define exactly one, e.g. CONFIG_MPC8540ADS.
-- Marvell Family Member
- CONFIG_SYS_MVFS - define it if you want to enable
- multiple fs option at one time
- for marvell soc family
-
- 85xx CPU Options:
CONFIG_SYS_PPC64
CONFIG_AT91_HW_WDT_TIMEOUT
specify the timeout in seconds. default 2 seconds.
-- U-Boot Version:
- CONFIG_VERSION_VARIABLE
- If this variable is defined, an environment variable
- named "ver" is created by U-Boot showing the U-Boot
- version as printed by the "version" command.
- Any change to this variable will be reverted at the
- next reset.
-
- Real-Time Clock:
When CONFIG_CMD_DATE is selected, the type of the RTC
CONFIG_EFI_PARTITION GPT partition table, common when EFI is the
bootloader. Note 2TB partition limit; see
disk/part_efi.c
- CONFIG_MTD_PARTITIONS Memory Technology Device partition table.
-
- If IDE or SCSI support is enabled (CONFIG_IDE or
CONFIG_SCSI) you must configure support for at
least one non-MTD partition type as well.
CONFIG_SUPPORT_EMMC_BOOT
Enable some additional features of the eMMC boot partitions.
- CONFIG_SUPPORT_EMMC_RPMB
- Enable the commands for reading, writing and programming the
- key for the Replay Protection Memory Block partition in eMMC.
-
- USB Device Firmware Update (DFU) class support:
CONFIG_DFU_OVER_USB
This enables the USB portion of the DFU USB class
the environment like the "source" command or the
boot command first.
- CONFIG_ENV_VARS_UBOOT_RUNTIME_CONFIG
-
- Define this in order to add variables describing certain
- run-time determined information about the hardware to the
- environment. These will be named board_name, board_rev.
-
CONFIG_DELAY_ENVIRONMENT
Normally the environment is loaded when the board is
-150 common/cmd_nand.c Incorrect FIT image format
151 common/cmd_nand.c FIT image format OK
-- legacy image format:
- CONFIG_IMAGE_FORMAT_LEGACY
- enables the legacy image format support in U-Boot.
-
- Default:
- enabled if CONFIG_FIT_SIGNATURE is not defined.
-
- CONFIG_DISABLE_IMAGE_LEGACY
- disable the legacy image format
-
- This define is introduced, as the legacy image format is
- enabled per default for backward compatibility.
-
- Standalone program support:
CONFIG_STANDALONE_LOAD_ADDR
for a more detailed description refer to doc/README.update.
- MTD Support (mtdparts command, UBI support)
- CONFIG_MTD_DEVICE
-
- Adds the MTD device infrastructure from the Linux kernel.
- Needed for mtdparts command support.
-
- CONFIG_MTD_PARTITIONS
-
- Adds the MTD partitioning infrastructure from the Linux
- kernel. Needed for UBI support.
-
-- UBI support
CONFIG_MTD_UBI_WL_THRESHOLD
This parameter defines the maximum difference between the highest
erase counter value and the lowest erase counter value of eraseblocks
CONFIG_SPL_NAND_DRIVERS
SPL uses normal NAND drivers, not minimal drivers.
+ CONFIG_SPL_NAND_IDENT
+ SPL uses the chip ID list to identify the NAND flash.
+ Requires CONFIG_SPL_NAND_BASE.
+
CONFIG_SPL_NAND_ECC
Include standard software ECC in the SPL
use an arch-specific makefile fragment instead, for
example if more than one image needs to be produced.
- CONFIG_FIT_SPL_PRINT
+ CONFIG_SPL_FIT_PRINT
Printing information about a FIT image adds quite a bit of
code to SPL. So this is normally disabled in SPL. Use this
option to re-enable it. This will affect the output of the
Begin and End addresses of the area used by the
simple memory test.
-- CONFIG_SYS_ALT_MEMTEST:
- Enable an alternate, more extensive memory test.
-
- CONFIG_SYS_MEMTEST_SCRATCH:
Scratch address used by the alternate memory test
You only need to set this if address zero isn't writeable
