Add Arm FF-A support implementing Arm Firmware Framework for Armv8-A v1.0
The Firmware Framework for Arm A-profile processors (FF-A v1.0) [1]
describes interfaces (ABIs) that standardize communication
between the Secure World and Normal World leveraging TrustZone
technology.
This driver uses 64-bit registers as per SMCCCv1.2 spec and comes
on top of the SMCCC layer. The driver provides the FF-A ABIs needed for
querying the FF-A framework from the secure world.
The driver uses SMC32 calling convention which means using the first
32-bit data of the Xn registers.
All supported ABIs come with their 32-bit version except FFA_RXTX_MAP
which has 64-bit version supported.
Both 32-bit and 64-bit direct messaging are supported which allows both
32-bit and 64-bit clients to use the FF-A bus.
FF-A is a discoverable bus and similar to architecture features.
FF-A bus is discovered using ARM_SMCCC_FEATURES mechanism performed
by the PSCI driver.
Clients are able to probe then use the FF-A bus by calling the DM class
searching APIs (e.g: uclass_first_device).
The Secure World is considered as one entity to communicate with
using the FF-A bus. FF-A communication is handled by one device and
one instance (the bus). This FF-A driver takes care of all the
interactions between Normal world and Secure World.
The driver exports its operations to be used by upper layers.
Exported operations:
- ffa_partition_info_get
- ffa_sync_send_receive
- ffa_rxtx_unmap
Generic FF-A methods are implemented in the Uclass (arm-ffa-uclass.c).
Arm specific methods are implemented in the Arm driver (arm-ffa.c).
For more details please refer to the driver documentation [2].

add support for x0-x17 registers used by the SMC calls
In SMCCC v1.2 [1] arguments are passed in registers x1-x17.
Results are returned in x0-x17.
This work is inspired from the following kernel commit:
arm64: smccc: Add support for SMCCCv1.2 extended input/output registers

- Actually merge the assorted K3 platform improvements that were
supposed to be in commit 247aa5a191 ("Merge branch
'2023-07-21-assorted-TI-platform-updates'")
In poking around it seems that many boards don't define a CONFIG_TARGET
Kconfig variable. This is not strictly necessary, but add an option to
buildman so these can be viewed.

Change -D to mean --debug for consistency with other tools. This is not a
commonly used option, so the impact should be minimal.

This is probably a little more efficient and it allows passing the object
to another function to write data. Convert config_out to use a string I/O
device.

Move more of the argument-building code into this function. Fix a missing
assignment for out_rel_dir too.
Rename the function since it now builds all the arguments.

This variable has a different meaning in the outer scope. Use a different
name to avoid confusion, or bugs.

Add a simple functional test for the --boards option. Fix the example in
the docs while we are here. Also improve the docs for Builder.count so it
is clearer what it contains.

Avoid an unnecessary local variable by moving this code to a function.
This fixes the pylint warning about too many local variables.

This is not needed until the builder is run. Move it there to reduce the
size of the do_buildman() function.

Move setting of show_bloat to adjust_options() and adjust how the commits
variable is set. Together these remove the pylint warning about too many
statements.

Do these all in the constructor, so it is consistent.

Commits are numbered for use in tests. Do this in determine_series() since
it is already dealing with the series.
