c9eff0a6b6 initcall: Support emitting events
At present the initcall list consists of a list of function pointers. Over
time the initcall lists will likely change to mostly emitting events,
since most of the calls are board- or arch-specific.

As a first step, allow an initcall to be an event type instead of a
function pointer. Add the required macro and update initcall_run_list() to
emit an event in that case, or ignore it if events are not enabled.

The bottom 8 bits of the function pointer are used to hold the event type,
with the rest being all ones. This should avoid any collision, since
initcalls should not be above 0xffffff00 in memory.

Convert misc_init_f over to use this mechanism.

Add comments to the initcall header file while we are here. Also fix up
the trace test to handle the change.

1312327680 initcall: Adjust the failure message and return value
Move the failure message outside the loop, so it is easier to follow the
code. Avoid swallowing the error code - just pass it along.

Drop the initcall-list address from the output. This is confusing since
we show two addresses. Really it is only the function address which is
useful, since it can be looked up in the map, e.g. with:

   grep -A1 -B1 serial_init u-boot.map

c7d4dfcd14 scripts/Makefile.lib: Embed capsule public key in platform's dtb
The EFI capsule authentication logic in u-boot expects the public key
in the form of an EFI Signature List(ESL) to be provided as part of
the platform's dtb. Currently, the embedding of the ESL file into the
dtb needs to be done manually.

Add a target for generating a dtsi file which contains the signature
node with the ESL file included as a property under the signature
node. Include the dtsi file in the dtb. This brings the embedding of
the ESL in the dtb into the U-Boot build flow.

The path to the ESL file is specified through the
CONFIG_EFI_CAPSULE_ESL_FILE symbol.

Both the Linux kernel and libbsd agree that strlcpy() should always
return strlen(src) and not include the NUL termination. The incorrect
U-Boot implementation makes it impossible to check the return value for
truncation, and breaks code written with the usual implementation in
mind (for example, fdtdec_add_reserved_memory() was subtly broken).

218b062e8f arm_ffa: efi: introduce FF-A MM communication
Add MM communication support using FF-A transport

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.

We tested the FF-A MM communication on the Corstone-1000 platform.

We ran the UEFI SCT test suite containing EFI setVariable, getVariable and
getNextVariable tests which involve FF-A MM communication and all tests
are passing with the current changes.

We made the SCT test reports (part of the ACS results) public following the
latest Corstone-1000 platform software release. Please find the test
reports at [1].

829445382c efi_loader: Fix memory corruption on 32bit systems
It's pretty unlikely that anyone is going to be using EFI authentication
on a 32bit system.  However, if you did, the efi_prepare_aligned_image()
function would write 8 bytes of data to the &efi_size variable and it
can only hold 4 bytes so that corrupts memory.

54edc37a22 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

c227ef7c4a 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.

395ab12b5f fwu: mtd: Fix dfu_alt_info generation for 2 images per bank
Code rewrites the last char of size with adding &. It is visible from
dfu_alt_info print before this patch:

Make dfu_alt_info: 'mtd nor0=bank0 raw 2320000 80000;bank1 raw 27a0000
8000&mtd nor0=bank0 raw 23a0000 4000000;bank1 raw 2820000 4000000'

And after it:
Make dfu_alt_info: 'mtd nor0=bank0 raw 2320000 80000;bank1 raw 27a0000
80000&mtd nor0=bank0 raw 23a0000 4000000;bank1 raw 2820000 4000000'

Size for bank0 and bank1 must be the same because it is the same image.

a6dd927f5b fwu: Allow code to properly decode trial state
Current code after capsule update (mtd write) is not changing active_index
in mdata to previous_active_index.
On the reboot this is shown but showing message
"Boot idx 1 is not matching active idx 0, changing active_idx"
which is changing active_idx and writing mdata to flash.

But when this message is visible it is not checking which state that images
are. If they have acceptance bit setup to yes everything is fine and valid
images are booted (doesn't mean the latest one).
But if acceptance bit is no and images are in trial state in_trial variable
is never setup. Which means that from new flashed image stable image can be
rewritten because in_trial is not setup properly.
