Introduce common variables to define a generic build instruction that is
then used in specific board specific description.
Labels are introduced in the evm.rst files to be then reused in variant
board documentation as well.
While at this, drop using ARCH=arm when building u-boot sources. This
practice has been discouraged for some time and can potentially create
problems with Kconfig rules related to aarch64. It's best to avoid
this approach.
We have duplication of sources which makes it hard to sustain across the
board, but at the same time, we'd like to ensure readers get specific
information without having to cross refer to different documentation to
get piecemeal information that they need to put together.

efi_loader: make efi_delete_handle() follow the EFI spec
The EFI doesn't allow removal of handles, unless all hosted protocols
are cleanly removed. Our efi_delete_handle() is a bit intrusive.
Although it does try to delete protocols before removing a handle,
it doesn't care if that fails. Instead it only returns an error if the
handle is invalid. On top of that none of the callers of that function
check the return code.
So let's rewrite this in a way that fits the EFI spec better. Instead
of forcing the handle removal, gracefully uninstall all the handle
protocols. According to the EFI spec when the last protocol is removed
the handle will be deleted. Also switch all the callers and check the
return code. Some callers can't do anything useful apart from reporting
an error. The disk related functions on the other hand, can prevent a
medium that is being used by EFI from removal.
The only function that doesn't check the result is efi_delete_image().
But that function needs a bigger rework anyway, so we can clean it up in
the future

efi_loader: device paths for special block devices
The UEFI specification does not provide node types matching UCLASS_BLKMAP,
UCLASS_HOST, UCLASS_VIRTIO block devices.
The current implementation uses VenHw() nodes with uclass specific GUIDs
and a single byte for the device number appended. This leads to unaligned
integers in succeeding device path nodes.
The current implementation fails to create unique device paths for block
devices based on other uclasses like UCLASS_PVBLOCK.
Let's use a VenHw() node with the U-Boot GUID with a length dividable by
four and encoding blkdesc->uclass_id as well as blkdesc->devnum.

Since commit 56670d6fb83f ("disk: part: use common api to lookup part

used to restrict the partition table type.
omap_mmc_get_part_size() and part_get_info_by_name() are the only
consumers.
omap_mmc_get_part_size() calls with part_type = PART_TYPE_EFI because at
the time of implementation a speed up could be gained by passing the
partition table type. After 5 years experience without this restriction
it looks safe to keep it that way.
part_get_info_by_name() uses PART_TYPE_ALL.
Move the logic of part_get_info_by_name_type() to part_get_info_by_name()
and replace the function in omap_mmc_get_part_size().

mailbox: k3-sec-proxy: Fill non-message tx data fields with 0x0
Sec proxy data buffer is 60 bytes with the last of the registers

challenge.
The backing memory for sec_proxy is regular memory, and all sec proxy
does is to trigger a burst of all 60 bytes of data over to the target
thread backing ring accelerator. It doesn't do a memory scrub when
it moves data out in the burst. When we transmit multiple messages,
remnants of previous message is also transmitted which results in
some random data being set in TISCI fields of messages that have been
expanded forward.
The entire concept of backward compatibility hinges on the fact that
the unused message fields remain 0x0 allowing for 0x0 value to be
specially considered when backward compatibility of message extension
is done.
So, instead of just writing the completion register, we continue
to fill the message buffer up with 0x0 (note: for partial message
involving completion, we already do this).
This allows us to scale and introduce ABI changes back also work with
other boot stages that may have left data in the internal memory.

To quote the author:
Adding support for Arm FF-A v1.0 (Arm Firmware Framework for Armv8-A) [A].
FF-A specifies interfaces that enable a pair of software execution
environments aka partitions to communicate with each other. A partition
could be a VM in the Normal or Secure world, an application in S-EL0, or
a Trusted OS in S-EL1.
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.

Class Index Probed Driver Name
-----------------------------------------------------------
...
firmware 0 [ + ] psci |-- psci
ffa 0 [ ] arm_ffa | `-- arm_ffa
...
Clients are able to probe then use the FF-A bus by calling the DM class
searching APIs (e.g: uclass_first_device).
This implementation of the specification provides support for Aarch64.
The FF-A driver uses the SMC ABIs defined by the FF-A specification to:
- Discover the presence of secure partitions (SPs) of interest
- Access an SP's service through communication protocols
(e.g: EFI MM communication protocol)
The FF-A support provides the following features:
- Being generic by design and can be used by any Arm 64-bit platform
- FF-A support can be compiled and used without EFI
- Support for SMCCCv1.2 x0-x17 registers
- Support for SMC32 calling convention
- Support for 32-bit and 64-bit FF-A direct messaging
- Support for FF-A MM communication (compatible with EFI boot time)
- Enabling FF-A and MM communication in Corstone1000 platform as a use case
- A Uclass driver providing generic FF-A methods.
- An Arm FF-A device driver providing Arm-specific methods and
reusing the Uclass methods.
- A sandbox emulator for Arm FF-A, emulates the FF-A side of the
Secure World and provides FF-A ABIs inspection methods.
- An FF-A sandbox device driver for FF-A communication with the
emulated Secure World. The driver leverages the FF-A Uclass to
establish FF-A communication.
- Sandbox FF-A test cases.
- A new command called armffa is provided as an example of how to
access the FF-A bus
For more details about the FF-A support please refer to [B] and refer to [C] for
how to use the armffa command.
Please find at [D] an example of the expected boot logs when enabling
FF-A support for a platform. In this example the platform is
Corstone1000. But it can be any Arm 64-bit platform.

[B]: doc/arch/arm64.ffa.rst

[D]: example of boot logs when enabling FF-A
This feature allows accessing MM partitions services through
EFI MM communication protocol. MM partitions such as StandAlonneMM
or smm-gateway secure partitions which reside in secure world.
An MM shared buffer and a door bell event are used to exchange
the data.
The data is used by EFI services such as GetVariable()/SetVariable()
and copied from the communication buffer to the MM shared buffer.
The secure partition is notified about availability of data in the
MM shared buffer by an FF-A message (door bell).
On such event, MM SP can read the data and updates the MM shared
buffer with the response data.
The response data is copied back to the communication buffer and
consumed by the EFI subsystem.
MM communication protocol supports FF-A 64-bit direct messaging.

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.
