Adds a command called "gpt transpose" which will swap the order two
partition table entries in the GPT partition table (but leaves them
pointing to the same locations on disk).
This can be useful for swapping bootloaders in systems that use an A/B
partitioning scheme where the bootrom is hard coded to look for the
bootloader in a specific index in the GPT partition table.

Some bootflows (such as EFI and ChromiumOS) delay reading the kernel until
it is needed to boot. This saves time when scanning and avoids needing to
allocate memory for something that may never be used.

Provide armffa command showcasing the use of the U-Boot FF-A support
armffa is a command showcasing how to invoke FF-A operations.
This provides a guidance to the client developers on how to
call the FF-A bus interfaces. The command also allows to gather secure
partitions information and ping these partitions. The command is also
helpful in testing the communication with secure partitions.
For more details please refer to the command documentation [1].
A Sandbox test is provided for the armffa command.

Some Linux parameters can be set automatically by U-Boot, if it knows the
device being used. For example, since U-Boot knows the serial console
being used, it can add parameters for earlycon and console.
Add support for this.
Note that this is an experimental feature and we will see how useful it
turns out to be. It is very handy for ChromeOS, since otherwise it is very
difficult to manually determine the UART address or port number,
particularly in a script.
Provide an example of how this is used with ChromeOS.

The read and write commands are, deliberately, implemented in the same
file, so that they stay feature-compatible (e.g. if someone implements
support for "read the full partition, however large that is", that
same syntax should also work for write). In order to ensure the
documentation for both are similarly kept in sync, and to avoid
duplication, document them both in read.rst, and add a stub write.rst
referring to read.rst.
