f13cd90762 mbedtls: access mbedtls private members in mscode and pkcs7 parser
U-Boot requires to access x509_internal.h, mbedtls_sha256_context and
mbedtls_sha1_context in the porting layer, and this requires to
enable MBEDTLS_ALLOW_PRIVATE_ACCESS.

Enable it to mscode and pkcs7_parser to fix a mbedtls internal building
error when X509 is selected.

Moreover, Move it to a separate file to avoid enabling it in multiple
places.

This serie adds the support of sha256_hmac and sha256_hkdf.
A first version was sent several months ago just before the
integration of mbedtls. This new version is based on mbedtls.

The first patch of this serie add the support of hkdf

4457e5c61d cyclic: introduce u-boot/schedule.h
I noticed an "unnecessary" include of <cyclic.h> in
global_data.h, in the sense that nothing in cyclic.h is needed in
order to define 'struct global_data'.

Well, it's not unnecessary, as it implicitly ensures that everybody
gets a declaration of schedule(), and schedule() is (obviously) called
all over the tree. Almost none of those places directly include
<cyclic.h>, but for historical reasons, many do include
<watchdog.h> (most schedule() instances are replacements of
WATCHDOG_RESET()).

However, very few TUs actually need the declarations of the
cyclic_register() and struct cyclic_info, and they also don't really
need anything from the watchdog.h header.

So introduce a new header which just contains a declaration of
schedule(), which can then be included from all the places that do
call schedule(). I removed the direct reference to cyclic_run(),
because we shouldn't have two public functions for doing roughly the
same without being very explicit about when one should call one or the
other.

Testing of later patches that explicitly include <schedule.h> when
schedule() is used revealed a problem with host tool build on win32,
which apparently picked up a host <schedule.h>. To avoid that problem,
put the new header in include/u-boot/ and hence make the include
statements say <u-boot/schedule.h>.

a3709638ec Merge patch series "aspeed: ast2700: Add Caliptra ECDSA driver"
Chia-Wei Wang <chiawei_wang@aspeedtech.com> says:

Aspeed AST2700 SoCs integrates the Caliptra secure IP, where an ECDSA384
signature verification HW interface is exported for SoC crypto needs.

This patch series firstly extends the FIT image signing/verify common
code to support the ECDSA384 algorithm. For better convenience, the
device tree for ECDSA public key storage is also revised by referring
to RSA implementations.

After the FIT common code revision, the driver is implemented for
AST2700 to leverage the Caliptra ECDSA384 signature verification.

These are verified by signed FIT images with the algorithm "sha384,ecdsa384".

5d1d98399f lib: Adapt digest header files to MbedTLS
Adapt digest header files to support both original libs and MbedTLS
by switching on/off MBEDTLS_LIB_CRYPTO.
Introduce <alg>_LEGACY kconfig for legacy hash implementations.
sha256.o should depend on SHA256 kconfig only but not SUPPORT_EMMC_RPMB,
SHA256 should be selected when SUPPORT_EMMC_RPMB is enabled instead.

`IS_ENABLED` or `CONFIG_IS_ENABLED` is not applicable here, since
including <linux/kconfig.h> causes undefined reference on schedule()
with sandbox build, as <linux/kconfig.h> includes <generated/autoconf.h>
which enables `CONFIG_HW_WATCHDOG` and `CONFIG_WATCHDOG` but no schedule()
are defined in sandbox build,
Thus we use `#if defined(CONFIG_MBEDTLS_LIB_CRYPTO)` instead.

bbacdd3ef7 Revert "Merge patch series "zlib: Address CVE-2016-9841""
This series brings our zlib code more up to date. However, it drops an
important performance improvement that is required on some of our
supported platforms in order to boot Linux before the watchdog resets
the system. Furthermore, the "post increment" version of this
performance loop was not tested, so while we can fix it, it would then
require re-testing all platforms. At this point in time, we will revert
updating zlib (which has had a potential security issue since 2016) and
fix this in the v2024.10 release.

26beded3d0 zlib: Remove incorrect ZLIB_VERSION
Get rid of zlib version which is not correct because of U-Boot related
changes and various CVE backports.

The change in inspired by Linux kernel commit 4f3865fb57a0 ("[PATCH]
zlib_inflate: Upgrade library code to a recent version") which described
ZLIB_VERSION removal as

"This patch also removes ZLIB_VERSION as it no longer has a correct value.
We don't need version checks anyway as the kernel's module handling will
take care of that for us.  This removal is also more in keeping with the
zlib author's wishes (http://www.zlib.net/zlib_faq.html#faq24) and I've
added something to the zlib.h header to note its a modified version."

Author describes wish to follow this guidance at
https://www.zlib.net/zlib_faq.html#faq24:
"The license says that altered source versions must be "plainly marked". So
what exactly do I need to do to meet that requirement?

You need to change the ZLIB_VERSION and ZLIB_VERNUM #defines in zlib.h. In
particular, the final version number needs to be changed to f, and an
identification string should be appended to ZLIB_VERSION. Version numbers
x.x.x.f are reserved for modifications to zlib by others than the zlib
maintainers. For example, if the version of the base zlib you are altering
is 1.2.3.4, then in zlib.h you should change ZLIB_VERNUM to 0x123f, and
ZLIB_VERSION to something like 1.2.3.f-zachary-mods-v3. You can also update
the version strings in deflate.c and inftrees.c."

But U-Boot is not exact version that's why following the same style which
has been used by Linux kernel where ZLIB_VERSION is completely removed.

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.

4deaff791c dm: hash: Add new UCLASS_HASH support
Add UCLASS_HASH for hash driver development. Thus the
hash drivers (SW or HW-accelerated) can be developed
in the DM-based fashion.

92c960bc1d lib: rsa: Remove #ifdefs from rsa.h
It is no longer necessary to implement rsa_() functions as no-ops
depending on config options. It is merely sufficient to provide the
prototypes, as the rsa code is no longer linked when unused.

ed6c9e0b66 lib: Add support for ECDSA image signing
mkimage supports rsa2048, and rsa4096 signatures. With newer silicon
now supporting hardware-accelerated ECDSA, it makes sense to expand
signing support to elliptic curves.

Implement host-side ECDSA signing and verification with libcrypto.
Device-side implementation of signature verification is beyond the
scope of this patch.

4c17e5f691 lib/rsa: Make fdt_add_bignum() available outside of RSA code
fdt_add_bignum() is useful for algorithms other than just RSA. To
allow its use for ECDSA, move it to a common file under lib/.

The new file is suffixed with '-libcrypto' because it has a direct
dependency on openssl. This is due to the use of the "BIGNUM *" type.

0bcb28dfb9 lib: Rename rsa-checksum.c to hash-checksum.c
rsa-checksum.c sontains the hash_calculate() implementations. Despite
the "rsa-" file prefix, this function is useful for other algorithms.

To prevent confusion, move this file to lib/, and rename it to
hash-checksum.c, to give it a more "generic" feel.
