Fastboot currently supports MMC and NAND flash devices. Similarly,
extend the support to SPI flash memories.
Note that in this initial implementation, partitions on the device are
not supported yet, but raw partitions can be set in U-Boot environment.
To define a raw partition descriptor, add an environment variable
similar to the MMC case:
```
fastboot_raw_partition_<raw partition name>=<offset> <size>
```
for example:
```
fastboot_raw_partition_boot=0x0 0x1000000
```

To enhance code organization, it is beneficial to consolidate all A/B
BCB management routines into a single super-command.
The 'bcb' command is an excellent candidate for this purpose.
This patch integrates the separate 'ab_select' command into the 'bcb'
group as the 'ab_select' subcommand, maintaining the same parameter list
for consistency.

As reported by Jonas Karlman this series breaks booting on some AArch64
platforms with common use cases. For now the best path forward is to
revert the series.
This reverts commit 777c28460947371ada40868dc994dfe8537d7115, reversing

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 <[email protected]> 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.

Some devices keep 2 copies of the bootloader_message in the misc
partition and write each in sequence when updating. This ensures that
there is always one valid copy of the bootloader_message. Teach u-boot
to optionally try a backup bootloader_message from a specified offset if
the primary one fails its CRC check.

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.

Quite a lot of the code in common/relates to booting and images. Before
adding more it seems like a good time to move the code into its own
directory.
Most files with 'boot' or 'image' in them are moved, except:
- autoboot.c which relates to U-Boot automatically running a script
- bootstage.c which relates to U-Boot timing
Drop the removal of boot* files from the output directory, since this
interfers with the symlinks created by tools and there does not appear
to be any such file from my brief testing.

hardware partition number may also be specified.
