163a0d7e2c efi_loader: add PE/COFF image measurement
"TCG PC Client Platform Firmware Profile Specification"
requires to measure every attempt to load and execute
a OS Loader(a UEFI application) into PCR[4].
This commit adds the PE/COFF image measurement, extends PCR,
and appends measurement into Event Log.

464010b0be efi_loader: Work-around build issue due to missing hash_calculate()
The hash_calculate() symbol is provided by hash-checksum.c. It depends
on hash_progressive_lookup_algo(), provided when CONFIG_HASH=y.

The issue is that hash_calculate() is used by the efi_loader,
irregardless of CONFIG_FIT_SIGNATURE. As pointed out in
commit 87316da05f ("lib: introduce HASH_CALCULATE option"),
enabling hash_calculate() based on CONFIG_FIT_SIGNATURE is incorrect.

To resolve this, use CONFIG_HASH as the compile switch for
hash-checksum.c. This ensures that all dependencies are compiled, and
is the most natural Kconfig to use.

There is the issue of having to 'select HASH' in a couple of places
that already 'select SHA256'. This is a deeper problem with how hashes
are organized, and fixing it is beyonf the scope of this change.

ec0512b173 Revert "lib: introduce HASH_CALCULATE option"
When we think of Kconfig, we usually think of features that we like
to enable or not. Ideally, we wouldn't use Kconfig to fix a build
issue, although sometimes it might make sense. With Kconfig it's hard
to guarantee that the fix is universal. We can only say that it works
for the set of tested configurations. In the majority of cases, it's
preferable to let the linker figure things out for us.

The reverted commit attempted to fix a build issue by adding an
invisible Kconfig option. This is wrong in several ways:

It invents a new Kconfig variable when CONFIG_HASH already
exists for the same purpose.
Second, hash-checksum.c makes use of the hash_progressive_lookup_algo()
symbol, which is only provided with CONFIG_HASH, but this dependency
was not expressed in the reverted patch.

It feels like Kconfig is turning into a listing of all available
source files, and a buffet to 'select' which ones to compile. The
purpose of this revert is to enable the next change to make use of
CONFIG_HASH instead of adding to Kconfig.

This reverts commit 87316da05f.

Coverity reported 3 warnings on the current code.

Fix the rest of the warnings by initializing the variables before

In order to avoid future warnings and errors initialize them to 0 within
the function as well, since the values are always OR'ed after querying the

46c3e29219 string: make memcpy(), memset(), memcmp() and memmove() visible for LTO
It seems that sometimes (happening on ARM64, for example with
turris_mox_defconfig) GCC, when linking with LTO, changes the symbol
names of some functions, for example lib/string.c's memcpy() function to
memcpy.isra.0.

This is a problem however when GCC for a code such as this:
	struct some_struct *info = get_some_struct();
	struct some struct tmpinfo;
	tmpinfo = *info;
emits a call to memcpy() by builtin behaviour, to copy *info to tmpinfo.

This then results in the following linking error:
  .../lz4.c:93: undefined reference to `memcpy'
  .../uuid.c:206: more undefined references to `memcpy' follow

GCC's documentation says this about -nodefaultlibs option:
  The compiler may generate calls to "memcmp", "memset", "memcpy" and
  "memmove".  These entries are usually resolved by entries in libc.
  These entry points should be supplied through some other mechanism
  when this option is specified.

Make these functions visible by using the __used macro to avoid this
error.

2052759a5e efi_loader: Don't stop EFI subsystem init if installing TCG2 fails
Up to now we are stopping the EFI subsystem if a TPMv2 exists but the
protocol fails to install.  Now that we've switched the config to 'default
y' the sandbox TPM fails, since it doesn't support all the required
capabilities of the protocol.

Not installing the protocol is not catastrophic.  If the protocol fails
to install the PCRs will never be extended to the expected values, so
some other entity later in the boot flow will eventually figure it out
and take the necessary actions.

While at it fix a corner case were the user can see an invalid error
message when the protocol failed to install.  We do have a tcg2_uninit()
which we call when the protocol installation fails.  There are cases though
that this might be called before the configuration table is installed (e.g
probing the TPM for capabilities failed).  In that case the user will see
"Failed to delete final events config table".  So stop printing it since it's
not an actual failure , simply because the config table was never installed
in the first place.

In order to stop printing it make efi_init_event_log() and create_final_event()
cleanup themselves and only call tcg2_uninit() when the protocol installation
fails.

When reading a directory, EFI_BUFFER_TOO_SMALL should be returned when
the supplied buffer is too small, so a use-case is to call
EFI_FILE_PROTOCOL.Read() with *buffer_size=0 and buffer=NULL to
obtain the needed size before doing the actual read.

So remove the check only for directory reading, file reading already

e2ae483c3b hash: Kconfig option for SHA512 hardware acceleration
Commit a479f103dc ("hash: Allow for SHA512 hardware implementations")
defined function definitions for hardware accelerated SHA384 and SHA512.
If CONFIG_SHA_HW_ACCEL=y, these functions are used.

We already have boards using CONFIG_SHA_HW_ACCEL=y but none implements the
new functions hw_sha384() and hw_sha512().

For implementing the EFI TCG2 protocol we need SHA384 and SHA512. The
missing hardware acceleration functions lead to build errors on boards like
peach-pi_defconfig.

Introduce a new Kconfig symbol CONFIG_SHA512_HW_ACCEL to control if the
functions hw_sha384() and hw_sha512() shall be used to implement the SHA384
and SHA512 algorithms.

feb7ac457c dm: core: Add address translation in fdt_get_resource
Today of_address_to_resource() is called only in
ofnode_read_resource() for livetree support and
fdt_get_resource() is called when livetree is not supported.

The fdt_get_resource() doesn't do the address translation
so when it is required, but the address translation is done
by ofnode_read_resource() caller, for example in
drivers/firmware/scmi/smt.c::scmi_dt_get_smt_buffer() {
...
	ret = ofnode_read_resource(args.node, 0, &resource);
	if (ret)
		return ret;

	faddr = cpu_to_fdt32(resource.start);
	paddr = ofnode_translate_address(args.node, &faddr);
...

The both behavior should be aligned and the address translation
must be called in fdt_get_resource() and removed for each caller.

Remove function invocations using the EFI_CALL macro for those
functions that do not have an EFI_ENTRY call in their definition. Such
functions can use u-boot api's which rely on u-boot global data(gd)
pointer. The Arm and RiscV architectures maintain a separate gd
pointer, one for u-boot, and a separate gd for the efi application.

Calling a function through the EFI_CALL macro changes the gd pointer
to that used for the efi application, with u-boot gd being
unavailable. Any function then trying to dereference u-boot's gd will
result in an abort.

Fix this issue by removing the EFI_CALL macro for all of such
functions which do not begin by an EFI_ENTRY function call.

fbc777429f lib/rsa: Use EVP_PKEY instead of RSA
Most modern OpenSSL engines have methods overridden at the EVP level rather
than at RSA level, to make these engines work properly with mkimage, the RSA
signing code needs to switch to using EVP_* APIs as much as possible.

The code ensures that every ESRT entry has a unique fw_class value.

Limitations:
- The ESRT is not updated if an FMP instance is uninstalled;
- the fields image_type and flags are in the current implementation left
undefined. Setting these values will require a per-platform function
that returns the image_type/flags as a function of the image fw_class.

53f6a5aa86 efi_loader: Replace config option for initrd loading
Up to now we install 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 continue the installation. It also makes the
feature hard to use, since we can either have a single initrd or we have
to recompile u-boot if the filename changes.

So let's introduce a different logic that will decouple the initrd
path from the config option we currently have.
When defining a UEFI BootXXXX we can use the filepathlist and store
a file path pointing to our initrd. Specifically the EFI spec describes:

"The first element of the array is a device path that describes the device
and location of the Image for this load option. Other device paths may
optionally exist in the FilePathList, but their usage is OSV specific"

When the EFI application is launched through the bootmgr, we'll try to
interpret the extra device path. If that points to a file that exists on
our disk, we'll now install the load_file2 and the efi-stub will be able
to use it.

This opens up another path using U-Boot and defines a new boot flow.
A user will be able to control the kernel/initrd pairs without explicit
cmdline args or GRUB.

  As with the /reserved-memory node, when booting via UEFI
  entries in the Memory Reservation Block must also be listed
  in the system memory map obtained via the GetMemoryMap() toi
  protect against allocations by UEFI applications. The memory
  reservation block entries should be listed with type
  EfiReservedMemoryType.

15bbcafab1 efi_loader: fix get_last_capsule()
fix get_last_capsule() leads to writes beyond the stack allocated buffer.
This was indicated when enabling the stack protector.

utf16_utf8_strcpy() only stops copying when reaching '\0'. The current
invocation always writes beyond the end of value[].

The output length of utf16_utf8_strcpy() may be longer than the number of
UTF-16 tokens. E.g has "CapsuleКиев" has 11 UTF-16 tokens but 15 UTF-8
tokens. Hence, using utf16_utf8_strcpy() without checking the input may
lead to further writes beyond value[].

The current invocation of strict_strtoul() reads beyond the end of value[].

A non-hexadecimal value after "Capsule" (e.g. "CapsuleZZZZ") must result in
an error. We cat catch this by checking the return value of strict_strtoul().

A value that is too short after "Capsule" (e.g. "Capsule0") must result in
an error. We must check the string length of value[].

e9adaa75bb smbios: Add more options for the BIOS version string
At present the version string is obtained from PLAIN_VERSION. Some boards
may want to configure this using the device tree, since the build system
can more easily insert things there after U-Boot itself is built. Add this
option to the code.

Also in some cases the version needs to be generated programmatically,
such as when it is stored elsewhere in the ROM and must be read first.
To handle this, keep a pointer around so that it can be updated later.
This works by storing the last string in the context, since it is easier
than passing out a little-used extra parameter.

Provide a function to update the version string.

02fc018a35 efi_loader: VenMedia device path node
The Load File2 protocol exposes a device path with a VenMedia() node. Hence
our implementation of the device path to text protocol should support this
node.

6bca36cee2 efi_selftest: use GUID to find ESP in dtbdump
If dtbdump.efi is loaded from memory when calling LoadImage the loaded
image protocol will not indicate the partition from where it was loaded.
In this case use the EFI system partition for the 'load' and 'save'
