d7d07a8b50 efi_loader: support boot from URI device path
This supports to boot from the URI device path.
When user selects the URI device path, bootmgr downloads
the file using wget into the address specified by loadaddr
env variable.
If the file is .iso or .img file, mount the image with blkmap
then try to boot with the default file(e.g. EFI/BOOT/BOOTAA64.EFI).
Since boot option indicating the default file is automatically
created when new disk is detected, system can boot by selecting
the automatically created blkmap boot option.
If the file is PE-COFF file, load and start the downloaded file.

The buffer used to download the ISO image file must be
reserved to avoid the unintended access to the image and
expose the ramdisk to the OS.
For PE-COFF file case, this memory reservation is done
in LoadImage Boot Service.

[Ilias fix a few memory leaks by replacing returns with gotos]

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.

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].

  Welcome to GRUB!

This would normally be fine as shim would continue to run grubaa64.efi,
but shim's error handling code for this case has a bug [1] that causes a
synchronous abort on at least chromebook_kevin (but apparently not on
QEMU arm64).

Double the default variable store size so the variables fit. There is a
note about this value matching PcdFlashNvStorageVariableSize when
EFI_MM_COMM_TEE is enabled, so keep the old default in that case.

448e2b6327 event: Correct dependencies on the EVENT framework
The event framework is just that, a framework. Enabling it by itself
does nothing, so we shouldn't ask the user about it. Reword (and correct
typos) around this the option and help text. This also applies to
DM_EVENT and EVENT_DYNAMIC. Only EVENT_DEBUG and CMD_EVENT should be
visible to the user to select, when EVENT is selected.

With this, it's time to address the larger problems. When functionality
uses events, typically via EVENT_SPY, the appropriate framework then
must be select'd and NOT imply'd. As the functionality will cease to
work (and so, platforms will fail to boot) this is non-optional and
where select is appropriate. Audit the current users of EVENT_SPY to
have a more fine-grained approach to select'ing the framework where
used. Also ensure the current users of event_register and also select
EVENT_DYNAMIC.

7f8967c2b8 blk: Rename HAVE_BLOCK_DEVICE
This option is fact really related to SPL. For U-Boot proper we always use
driver model for block devices, so CONFIG_BLK is enabled if block devices

It is only for SPL that we have two cases:

- SPL_BLK is enabled, in which case we use driver model and blk-uclass.c
- SPL_BLK is not enabled, in which case (if we need block devices) we must
  use blk_legacy.c

Rename the symbol to SPL_LEGACY_BLOCK to make this clear. This is
different enough from BLK and SPL_BLK that there should be no confusion.

a9e6f01a94 efi: Define set_dfu_alt_info() for boards with UEFI capsule update enabled
Currently, there are a bunch of boards which enable the UEFI capsule
update feature. The actual update of the firmware images is done
through the dfu framework which uses the dfu_alt_info environment
variable for getting information on the update, like device, partition
number/address etc. The dfu framework allows the variable to be set
through the set_dfu_alt_info function defined by the platform, or if
the function is not defined, it gets the variable from the
environment. Using the value set in the environment is not very
robust, since the variable can be modified from the u-boot command
line and this can cause an incorrect update.

To prevent this from happening, define the set_dfu_alt_info function
when the capsule update feature is enabled. A weak function is defined
which sets the dfu_alt_info environment variable by getting the string
for the variable from the platform.

c779e0d923 efi_loader: Drop code that doesn't work with driver model
This code should never have been added as it builds a new feature on top
of legacy code. This has already been improved with the dependency on BLK.

Add a dependency on DM_ETH also, to avoid needing to deal with this old
code.

Boards which want EFI_LOADER should migrate to driver model first.

1eccbb16a2 efi: Correct dependency on FIT_SIGNATURE
At present EFI_SECURE BOOT selects RSA but does not necessarily enable
FIT_SIGNATURE. Mostly this is fine, but a few boards do not enable it,
so U-Boot tries to do RSA verification when loading FIT images, but it
is not enabled.

This worked because the condition for checking the RSA signature is
wrong in the fit_image_verify_with_data() function. In order to fix it
we need to fix this dependency. Make sure that FIT_SIGNATURE is enabled
so that RSA can be used.

It might be better to avoid using 'select' in this situation.

465bff8b10 Kconfig: Drop duplicate 'select SHA512' instances
When dropping SHA512_ALGO in general, we didn't catch some cases where
an option was selecting  both SHA512 and SHA512_ALGO and caused them to
select SHA512 twice.  Kconfig doesn't complain, but this is still wrong
and should be corrected.

e60e449931 lib: Drop SHA512_ALGO in lieu of SHA512
SHA512_ALGO was used as a "either SHA512 or SHA384", although the
implementations of these two algorithms share a majority of code.

From a Kconfig interface perspective, it makes sense to present two
distinct options. This requires #ifdefing out the SHA512
implementation from sha512.c. The latter doesn't make any sense.

It's reasonable to say in Kconfig that SHA384 depends on SHA512, and
seems to be the more polite way to handle the selection.

Thus, automatically select SHA512 when SHA384 is enabled.

ddf67daac3 efi_capsule: Move signature from DTB to .rodata
The capsule signature is now part of our DTB.  This is problematic when a
user is allowed to change/fixup that DTB from U-Boots command line since he
can overwrite the signature as well.
So Instead of adding the key on the DTB, embed it in the u-boot binary it
self as part of it's .rodata.  This assumes that the U-Boot binary we load
is authenticated by a previous boot stage loader.

0fa5020c02 efi_loader: Allow capsule update on-disk without checking OsIndications
Although U-Boot supports capsule update on-disk, it's lack of support for
SetVariable at runtime prevents applications like fwupd from using it.

In order to perform the capsule update on-disk the spec says that the OS
must copy the capsule to the \EFI\UpdateCapsule directory and set a bit in
the OsIndications variable.  The firmware then checks for the
EFI_OS_INDICATIONS_FILE_CAPSULE_DELIVERY_SUPPORTED bit in OsIndications
variable, which is set by the submitter to trigger processing of the
capsule on the next reboot.

Let's add a config option which ignores the bit and just relies on the
capsule being present. Since U-Boot deletes the capsule while processing
it, we won't end up applying it multiple times.

Note that this is allowed for all capsules. In the future, once
authenticated capsules are fully supported, we can limit the functionality
to those only.

b891ff18f8 efi_loader: Force a single FMP instance per hardware store
Chapter 23 of the EFI spec (rev 2.9) says:
"A specific updatable hardware firmware store must be represented by
exactly one FMP instance".
This is not the case for us, since both of our FMP protocols can be
installed at the same time because they are controlled by a single
'dfu_alt_info' env variable.
So make the config options depend on each other and allow the user to
install one of them at any given time.  If we fix the meta-data provided
by the 'dfu_alt_info' in the future,  to hint about the capsule type
(fit or raw) we can revise this and enable both FMPs to be installed, as
long as they target different firmware hardware stores

Note that we are not using a Kconfig 'choice' on purpose, since we
want to allow both of those to be installed and tested in sandbox
