3e50deece0 lib: aes: build failure with DEBUG=1
Building fails with DEBUG=1:

lib/aes.c: In function ‘debug_print_vector’:
lib/aes.c:622:45: error:

[-Werror=pointer-to-int-cast]
  622 |  printf("%s [%d] @0x%08x", name, num_bytes, (u32)data);

Pointers can only be cast to (uintptr_t). But anyway we have
%p for printing pointers.

976a68a20d string: Use memcpy() within memmove() when we can
A common use of memmove() can be handled by memcpy(). Also memcpy()
includes an optimization for large sizes: it copies a word at a time. So
we can get a speed-up by calling memcpy() to handle our move in this case.

Update memmove() to call also memcpy() if the source don't overlap
the destination (src + count <= dest).

c0364ce1c6 doc/README.gpt: define partition type GUID for U-Boot environment
When setting aside a GPT partition for holding the U-Boot environment,
having a partition type GUID [1] indicating "Linux filesystem" (as
most tools default to) is somewhat misleading - and there's no other
well-known type GUID that is better suited. So to have a canonical
value to put into the type field, define

    3de21764-95bd-54bd-a5c3-4abe786f38a8

to mean a partition holding a U-Boot environment.

This is a v5 namespace-name GUID [2], generated [3] from a namespace
of "25cbcde0-8642-47c6-a298-1a3a57cd256b" and name "U-Boot
environment".

Should future type GUIDs be defined in the context of U-Boot, it's
sensible to use that same namespace GUID.

31ce367cd1 lib/uuid.c: change prototype of uuid_guid_get_str()
There's no reason to require an appropriately sized output parameter
for the string, that's error-prone should the table ever grow an
element with a longer string. We can just return the const char*
pointer directly.

Update the only caller accordingly, and get rid of pointless ifdeffery
in the header so that the compiler always sees a declaration and can
thus do type-checking, whether or not PARTITION_TYPE_GUID is enabled
or not.

8e70f1cb3f efi_selftest: dtbdump support EFI_DT_FIXUP_PROTOCOL
The dtbdump.efi binary can already be used to dump the configuration table
with the device-tree to a file.

With this patch a device-tree file can be loaded. The EFI_DT_FIXUP_PROTOCOL
is called to

* apply U-Boot's fix-ups
* let U-Boot make memory reservations as required by the device-tree
* install the new device-tree as configuration table

In a next step this configuration table can be dumped.

A dtbdump.efi session would look like:

    DTB Dump
    ========

    => load test.dtb
    device-tree installed
    => save fixed-up.dtb
    fixed-up.dtb written
    => exit

4366a2440a crypto: Fix the logic to calculate hash with authattributes set
RFC 2315 Section 9.3 describes the message digesting process. The
digest calculated depends on whether the authenticated attributes are
present. In case of a scenario where the authenticated attributes are
present, the message digest that gets signed and is part of the pkcs7
message is computed from the auth attributes rather than the contents
field.

Check if the auth attributes are present, and if set, use the auth
attributes to compute the hash that would be compared with the
encrypted hash on the pkcs7 message.

47d2b3b9c9 efi_loader: Remove unconditional installation of file2 protocol for initrd
Up to now we install the EFI_LOAD_FILE2_PROTOCOL to load an initrd
unconditionally. Although we correctly return various EFI exit codes
depending on the file status (i.e EFI_NO_MEDIA, EFI_NOT_FOUND etc), the
kernel loader only falls back to the cmdline interpreted initrd if the
protocol is not installed.

This creates a problem for EFI installers, since they won't be able to
load their own initrd and start the installation.

A following patch introduces a different logic where we search for an
initrd path defined in an EFI variable named 'Initrd####'.
If the bootmgr is used to launch the EFI payload, we'll will try to match
the BootCurrent value and find the corresponding initrd
(i.e Boot0000 -> Initrd0000 etc). If the file is found, we'll install
the required protocol which the kernel's efi-stub can use and load our
initrd.

c589132a1d fdt: Use phandle to distinguish DT nodes with same name
While assigning the sequence number to subsystem instances by reading the
aliases property, only DT nodes names are compared and not the complete
path. This causes a problem when there are two DT nodes with same name but
have different paths.

In arch/arm/dts/k3-am65-main.dtsi there are two USB controllers with the
same device tree node name but different path. When aliases are defined for
these USB controllers then fdtdec_get_alias_seq() fails to pick the correct
instance for a given index.

fdt_path_offset() function is slow and this would effect the U-Boot
startup. To avert the time penalty on all boards, apply this extra check
only when required by using a config option.

Fix it by comparing the phandles of DT nodes after the node names match,
under a config option.

caa4daa2ae dm: treewide: Rename 'platdata' variables to just 'plat'
We use 'priv' for private data but often use 'platdata' for platform data.
We can't really use 'pdata' since that is ambiguous (it could mean private
or platform data).

Rename some of the latter variables to end with 'plat' for consistency.

41575d8e4c dm: treewide: Rename auto_alloc_size members to be shorter
This construct is quite long-winded. In earlier days it made some sense
since auto-allocation was a strange concept. But with driver model now
used pretty universally, we can shorten this to 'auto'. This reduces
verbosity and makes it easier to read.

Coincidentally it also ensures that every declaration is on one line,
thus making dtoc's job easier.

04cc7914f2 efi_selftest: implement exception test for sandbox
Provide a unit test that causes an illegal instruction to occur.

The test can be run with the following commands:

    => setenv efi_selftest exception
    => bootefi selftest

This might be the output:

    Executing 'exception'
    EFI application triggers exception.
    Illegal instruction
    pc = 0x1444d016, pc_reloc = 0xffffaa078e8dd016
    UEFI image [0x0000000000000000:0xffffffffffffffff] '/\selftest'
    UEFI image [0x000000001444b000:0x0000000014451fff] pc=0x2016 '/bug.efi'
    Resetting ...

It would tell us that the exception was triggered by an instruction
0x2016 bytes after the load address of the binary with filename /bug.efi.

264485131c efi_loader: link partition to block device
We provide a UEFI driver for block devices. When ConnectController() is
called for a handle with the EFI_BLOCK_IO_PROTOCOL this driver creates the
partitions. When DisconnectController() is called the handles for the
partitions have to be deleted. This requires that the child controllers
(partitions) open the EFI_BLOCK_IO_PROTOCOL of the controller (block IO
device) with attribute EFI_OPEN_PROTOCOL_BY_CHILD_CONTROLLER.
