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.

e7d285b2f3 image: Use the correct checks for CRC32
Add a host Kconfig for CRC32. With this we can use CONFIG_IS_ENABLED(CRC32)
directly in the host build, so drop the unnecessary indirection.

Add a few more conditions to SPL_CRC32 to avoid build failures as well as
TPL_CRC32. Also update hash.c to make crc32 optional and to actually take
notice of SPL_CRC32.

2c21256b27 hash: Use Kconfig to enable hashing in host tools and SPL
At present when building host tools, we force CONFIG_SHAxxx to be enabled
regardless of the board Kconfig setting. This is done in the image.h
header file.

For SPL we currently just assume the algorithm is desired if U-Boot proper
enables it.

Clean this up by adding new Kconfig options to enable hashing on the host,
relying on CONFIG_IS_ENABLED() to deal with the different builds.

Add new SPL Kconfigs for hardware-accelerated hashing, to maintain the
current settings.

This allows us to drop the image.h code and the I_WANT_MD5 hack.

603d15a572 spl: cypto: Bring back SPL_ versions of SHA
Unfortunately these were removed by mistake. This means that adding hash
support to SPL brings in all software algorithms, with a substantial
increase in code size.

The origin of the problem was renaming them to SPL_FIT_xxx and then these
were removed altogether in a later commit.

Add them back. This aligns with CONFIG_MD5, for example, which has an SPL
variant.

5a4f10d71b gzip: Avoid use of u64
The gzip API uses the u64 type in it, which is not available in the host
build. This makes it impossible to include the header file.

We could make this type available, but it seems unnecessary. Limiting the
compression size to that of the 'unsigned long' type seems good enough. On
32-bit machines the limit then becomes 4GB, which likely exceeds available
RAM anyway, therefore it should be sufficient. On 64-bit machines this is
effectively u64 anyway.

Update the header file and implementation to use 'ulong' instead of 'u64'.

Add a definition of u32 for the cases that seem to need exactly that
length. This should be safe enough.

94d0a2efc0 zstd: Create a function for use from U-Boot

with other compression algorithms. Make use of of this from the image

67bc59df05 Add support for an owned buffer
When passing a data buffer back from a function, it is not always clear
who owns the buffer, i.e. who is responsible for freeing the memory used.
An example of this is where multiple files are decompressed from the
firmware image, using a temporary buffer for reading (since the
compressed data has to live somewhere) and producing a temporary or
permanent buffer with the resuilts.

Where the firmware image can be memory-mapped, as on x86, the compressed
data does not need to be buffered, but the complexity of having a buffer
which is either allocated or not, makes the code hard to understand.

Introduce a new 'abuf' which supports simple buffer operations:

- encapsulating a buffer and its size
- either allocated with malloc() or not
- able to be reliably freed if necessary
- able to be converted to an allocated buffer if needed

This simple API makes it easier to deal with allocated and memory-mapped
buffers.

This config is only used by three boards with this SOC. Most other

f6953047cb lib: optee: Remove CONFIG_OPTEE_LOAD_ADDR
This value is not used by u-boot, and it should not. The load address
of an OPTEE image is defined by said image. Either a uImage or a FIT
will have a defined load address and entry point. Those values are the
correct ones, not CONFIG_OPTEE_LOAD_ADDR.

Commit f25006b96e ("optee: Add CONFIG_OPTEE_LOAD_ADDR") justifies
this config by requiring its presence in u-boot's .config for other
images as part of a larger build, claiming it is "the best way".

This argument is not persuasive. U-boot's configuration is driven by
platform requirements, not the other way around. It seems more likely
that the argument is conflating tooling issues with Kconfig. Yocto and
buildroot have excellent mechanisms for defining values across the
board (pun intended). u-boot's Kconfig is the wrong place to do it.

Furthermore, it is not "best" for u-boot because it hardcodes a value
which is then not used. In fact the load address that u-boot uses is
the one derived from the OPTEE image.

Confused yet? I sure was. To prevent future confusion, remove
CONFIG_OPTEE_LOAD_ADDR.

26fc66709c lib: optee: Avoid CONFIG_TZDRAM_* in optee_verify_bootm_image()
The configs TZDRAM_BASE and TZDRAM_SIZE are expected to describe the
memory allocated to the OPTEE region. according to according to commit
c5a6e8bd00 ("optee: Add optee_verify_bootm_image()"). The TZDRAM is
with some limitations, described by "/reserved-memory" nodes in the
devicetree.

Consequently TZDRAM_BASE and TZDRAM_SIZE can point to imaginary
regions which have nothing to do with actual DRAM. They are not used
to configure the hardware or set up the Trust Zone Controller (TZC)
for OP-TEE -- the devicetree values are used instead.

When a valid OP-TEE image does not fall within the region described by
these configs, u-boot will refuse to load it. In fact, it mostly
serves to cause "bootm" to reject perfectly good OP-TEE images.

Ironically, someone has to correctly configure the devicetree for
TZDRAM, then go back and enter the same information in Kconfig for
"bootm". To remedy this, do not use TZDRAM_BASE and TZDRAM_SIZE in the
verification of OPTEE images.

51827f9a8b lib: optee: remove the duplicate CONFIG_OPTEE
The configuration CONFIG_OPTEE is defined 2 times:
1- in lib/optee/Kconfig for support of OPTEE images loaded by bootm command
2- in drivers/tee/optee/Kconfig for support of OP-TEE driver.

It is abnormal to have the same CONFIG define for 2 purpose;
and it is difficult to managed correctly their dependencies.

Moreover CONFIG_SPL_OPTEE is defined in common/spl/Kconfig
to manage OPTEE image load in SPL.

This definition causes an issue with the macro CONFIG_IS_ENABLED(OPTEE)
to test the availability of the OP-TEE driver.

This patch cleans the configuration dependency with:
- CONFIG_OPTEE_IMAGE (renamed) => support of OP-TEE image in U-Boot
- CONFIG_SPL_OPTEE_IMAGE (renamed) => support of OP-TEE image in SPL
- CONFIG_OPTEE (same) => support of OP-TEE driver in U-Boot
- CONFIG_OPTEE_LIB (new) => support of OP-TEE library

After this patch, the macro have the correct behavior:
- CONFIG_IS_ENABLED(OPTEE_IMAGE) => Load of OP-TEE image is supported
- CONFIG_IS_ENABLED(OPTEE) => OP-TEE driver is supported

this field is populated with the count of all algorithms supported

de41f0ee0d image: rsa: Move padding_algos to linker lists
We are not guaranteed to have the padding_pkcs_15_verify symbol since
commit 92c960bc1d ("lib: rsa: Remove #ifdefs from rsa.h"), and
commit 61416fe9df ("Kconfig: FIT_SIGNATURE should not select RSA_VERIFY")

The padding_algos only make sense with RSA verification, which can now
be disabled in lieu of ECDSA. In fact this will lead to build failures
because of the missing symbol mentioned earlier.

To resolve this, move the padding_algos to a linker list, with
declarations moved to rsa_verify.c. This is consistent with commit
6909edb4ce ("image: rsa: Move verification algorithm to a linker list")

One could argue that the added #ifdef USE_HOSTCC is ugly, and should
be hidden within the U_BOOT_PADDING_ALGO() macro. However, this would
be inconsistent with the "cryptos" list. This logic for was not
previously explored:

Without knowledge of the U_BOOT_PADDING_ALGO() macro, its use is
similar to something being declared. However, should #ifndef
USE_HOSTCC be part of the macro, it would not be obvious that it
behaves differently on host code and target code. Having the #ifndef
outside the macro makes this obvious.

Also, the #ifdef is not always necessary. For example ecda-verify
makes use of U_BOOT_CRYPTO_ALGO() without any accompanying #ifdefs.
The fundamental issue is a lack of separation of host and target code
in rsa_verify. Therefore, the declaration of a padding algo with the
external #ifdef is more readable and consistent.

fe54aeaa4a common: Move MD5 hash to hash_algo[] array.
MD5 is being called directly in some places, but it is not available
via hash_lookup_algo("md5"). This is inconsistent with other hasing
routines. To resolve this, add an "md5" entry to hash_algos[].

The #ifdef clause looks funnier than those for other entries. This is
because both MD5 and SPL_MD5 configs exist, whereas the other hashes
do not have "SPL_" entries. The long term plan is to get rid of the
ifdefs, so those should not be expected to survive much longer.

The md5 entry does not have .hash_init/update/finish members. That's
okay because hash_progressive_lookup_algo() will catch that, and
return -EPROTONOSUPPORT, while hash_lookup_algo() will return the
correct pointer.

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.

Older OpenSSL and libressl versions have a slightly different API.
This require #ifdefs to support. However, we still can't support it
because the ECDSA path does not compile with these older versions.
These #ifdefs are truly a vestigial appendage.

Alternatively, the ECDSA path could be updated for older libraries,
but this requires significant extra code, and #ifdefs. Those libraries
are over three years old, and there concerns whether it makes sense to
build modern software for real world use against such old libraries.

Thusly, remove #ifdefs and code for old OpenSSL and LibreSSL support.

f52352f65e display_options: Do not use %llu in print_size
tiny-printf variant doesn't know how to handle %llu format string, but both
tiny-printf and print_size can meet in SPL when TFTP is used to obtain main

when printf is catched in infinite loop.

To avoid such issues and make print_size function tiny-printf friendly, use %u
instead of %luu. Note, that the size value is guaranteed to be less than 1024

e6951139c0 lib: Allow using 0x when a decimal value is requested
U-Boot mostly uses hex for value input, largely because addresses are much
easier to understand in hex.

But in some cases a decimal value is requested, such as where the value is
small or hex does not make sense in the context. In these cases it is
sometimes useful to be able to provide a hex value in any case, if only to
resolve any ambiguity.

Add this functionality, for increased flexibility.

96b23440c1 lib: Drop unnecessary check for hex digit
If we see 0x then we can assume this is the start of a hex value. It
does not seem necessary to check for a hex digit after that since it will
happen when parsing the value anyway.

Drop this check to simplify the code and reduce size. Add a few more test
cases for when a 0x prefix is used.

11275e4f72 smbios: Fix calculating BIOS Release Date
BIOS Release Date must be in format mm/dd/yyyy and must be release date.
U-Boot currently sets BIOS Release Date from U_BOOT_DMI_DATE macro which is
generated from current build timestamp.

Fix this issue by setting U_BOOT_DMI_DATE macro to U-Boot version which is
better approximation of U-Boot release date than current build timestamp.
Current U-Boot versioning is in format yyyy.mm so as a day choose 01.

Some operating systems are using BIOS Release Date for detecting when was
SMBIOS table filled or if it could support some feature (e.g. BIOS from
1990 cannot support features invented in 2000). So this change also ensures
that recompiling U-Boot from same sources but in different year does not
change behavior of some operating systems.

Macro U_BOOT_DMI_DATE is not used in other file than lib/smbios.c
so remove it from global autogenerated files and also from Makefile.

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.

There's currently no user of %p[iI]6, so including ip6_addr_string()
in the image is a waste of bytes. It's easy enough to have the
compiler elide it without removing the code completely.

The closest I can find to anybody "handling" ipv6 in U-Boot currently
is in efi_net.c which does

        if (ipv6) {
                ret = EFI_UNSUPPORTED;

As indicated in the comment, it can easily be put back, but preferably
under a config knob.
