- Error Recovery:
CONFIG_PANIC_HANG
- CONFIG_SYS_MONITOR_BASE:
Physical start address of boot monitor code (set by
make config files to be same as the text base address
- (TEXT_BASE) used when linking) - same as
+ (CONFIG_SYS_TEXT_BASE) used when linking) - same as
CONFIG_SYS_FLASH_BASE when booting from flash.
- CONFIG_SYS_MONITOR_LEN:
all data for the Linux kernel must be between "bootm_low"
and "bootm_low" + CONFIG_SYS_BOOTMAPSZ.
+- CONFIG_SYS_BOOT_RAMDISK_HIGH:
+ Enable initrd_high functionality. If defined then the
+ initrd_high feature is enabled and the bootm ramdisk subcommand
+ is enabled.
+
+- CONFIG_SYS_BOOT_GET_CMDLINE:
+ Enables allocating and saving kernel cmdline in space between
+ "bootm_low" and "bootm_low" + BOOTMAPSZ.
+
+- CONFIG_SYS_BOOT_GET_KBD:
+ Enables allocating and saving a kernel copy of the bd_info in
+ space between "bootm_low" and "bootm_low" + BOOTMAPSZ.
+
- CONFIG_SYS_MAX_FLASH_BANKS:
Max number of Flash memory banks
- CONFIG_ENV_SIZE:
These two #defines specify the offset and size of the environment
- area within the first NAND device.

- - CONFIG_ENV_OFFSET_REDUND
+ - CONFIG_ENV_OFFSET_REDUND (optional):
This setting describes a second storage area of CONFIG_ENV_SIZE
- size used to hold a redundant copy of the environment data,
- so that there is a valid backup copy in case there is a
- power failure during a "saveenv" operation.
-
- Note: CONFIG_ENV_OFFSET and CONFIG_ENV_OFFSET_REDUND must be aligned

+
+ - CONFIG_ENV_RANGE (optional):
+
+ Specifies the length of the region in which the environment
+ can be written. This should be a multiple of the NAND device's
+ block size. Specifying a range with more erase blocks than
+ are needed to hold CONFIG_ENV_SIZE allows bad blocks within
+ the range to be avoided.
+
+ - CONFIG_ENV_OFFSET_OOB (optional):
+
+ Enables support for dynamically retrieving the offset of the
+ environment from block zero's out-of-band data. The
+ "nand env.oob" command can be used to record this offset.
+ Currently, CONFIG_ENV_OFFSET_REDUND is not supported when
+ using CONFIG_ENV_OFFSET_OOB.
