Currently, fastboot protocol in U-Boot has no opportunity
to execute vendor custom code with verifed boot. This patch
introduce new fastboot subcommand fastboot oem board:<cmd>,
which allow to run custom oem_board function.
Default implementation is __weak. Vendor must redefine it in
board/ folder with his own logic.
For example, some vendors have their custom nand/emmc partition
flashing or erasing. Here some typical command for such use cases:
- flashing:
$ fastboot stage bootloader.img
$ fastboot oem board:write_bootloader
- erasing:
$ fastboot oem board:erase_env

Simon Glass <sjg@chromium.org> says:
This series is the culmanation of the current line of refactoring
series. It adjusts pxe to call the booting functionality directly
rather than going through the command-line interface.
With this is is possible to boot using the extlinux bootmeth without
the command line enabled.
It also updates fastboot to do a similar thing.
The fastboot 'boot' command only supports running a U-Boot command if
CONFIG_CMDLINE is enabled. Mention this in the documentation.

This adds the UUU UCmd functionality as an OEM command. While the
fastboot tool allows sending arbitrary commands as long as they are
prefixed with "oem". This allows running generic U-Boot commands over
fastboot without UUU, which is especially useful when not using USB.
This is really the route we should have gone in the first place when
adding these commands.
While we're here, clean up the UUU Kconfig a bit.

[lukma - Kconfig adjustments after merging this patch]
Add support for defining raw fastboot partitions in eMMC by specifying
the offset and size in an environment variable. Optionally, the eMMC
hardware partition number may also be specified.
This makes it possible to e.g. update only part of the eMMC boot
partition, instead of having to write the entire partition.
