+- Removal of commands
+ If no commands are needed to boot, you can disable
+ CONFIG_CMDLINE to remove them. In this case, the command line
+ will not be available, and when U-Boot wants to execute the
+ boot command (on start-up) it will call board_run_command()
+ instead. This can reduce image size significantly for very
+ simple boot procedures.

- Regular expression support:
CONFIG_REGEX
If this variable is defined, U-Boot is linked against
CONFIG_MTD_PARTITIONS Memory Technology Device partition table.
If IDE or SCSI support is enabled (CONFIG_CMD_IDE or
- CONFIG_CMD_SCSI) you must configure support for at
+ CONFIG_SCSI) you must configure support for at
least one non-MTD partition type as well.
- IDE Reset method:
The DIU driver will look for the 'video-mode' environment
variable, and if defined, enable the DIU as a console during
- boot. See the documentation file README.video for a
+ boot. See the documentation file doc/README.video for a
description of this variable.
- LCD Support: CONFIG_LCD
If this option is set, then U-Boot will prevent the environment
variable "splashimage" from being set to a problematic address
- (see README.displaying-bmps).
+ (see doc/README.displaying-bmps).
This option is useful for targets where, due to alignment
restrictions, an improperly aligned BMP image will cause a data
abort. If you think you will not have problems with unaligned
consider that a completely unreadable NAND block is bad,
and thus should be skipped silently.
+ CONFIG_SPL_ABORT_ON_RAW_IMAGE
+ When defined, SPL will proceed to another boot method
+ if the image it has loaded does not have a signature.

CONFIG_SPL_RELOC_STACK
Adress of the start of the stack SPL will use after
relocation. If unspecified, this is equal to
