spl: Avoid including hash algorithms which are not wanted

2025-02-03T22:01:36+00:00

Update the build rule so that hash algorithms are only included in an
SPL build if they are requested. This helps to reduce code size.

lib: Allow crc16 code to be dropped

2025-02-03T22:00:42+00:00

This code is not necessarily needed in VPL, even if SPL uses it, so
adjust the rules to allow it to be dropped.

Do the same for the hash API.

Merge patch series "upl: Prerequite patches for updated spec"

2025-01-22T23:08:47+00:00

Simon Glass  says:

The current UPL spec[1] has been tidied up and improved over the last
year, since U-Boot's original UPL support was written.

This series includes some prerequisite patches needed for the real UPL
patches. It is split from [2]

emulation: Use bloblist to hold tables

2025-01-22T23:08:23+00:00

QEMU can have its own internal ACPI and SMBIOS tables. At present U-Boot
copies out the SMBIOS tables but points directly to the ACPI ones.

The ACPI tables are not aligned on a 4KB boundary, which means that UPL
cannot use them directly, since it uses a reserved-memory node for the
tables and that it assumed (by EDK2) to be 4KB-aligned.

On x86, QEMU provides the tables in a mapped memory region and U-Boot
makes use of these directly, thus making it difficult to use any common
code.

Adjust the logic to fit within the existing table-generation code. Use a
bloblist always and ensure that the ACPI tables is placed in an aligned
region. Set a size of 8K for QEMU. This does not actually put all the
tables in one place, for QEMU, since it currently adds a pointer to the
tables in QFW.

On ARM, enable bloblist so that SMBIOS tables can be added to the
bloblist.

Merge patch series "add the support of sha256_hmac and sha256_hkdf"

2025-01-18T23:13:01+00:00

Philippe Reynes  says:

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
using mbedtls.

lib: sha256: move common function to sha256_common.c

2025-01-18T23:12:47+00:00

The function sha256_csum_wd is defined in lib/sha256.c
and in lib/mbedtls/sha256.c. To avoid duplicating this
function (and future function), we move this function
to the file lib/sha256_common.c

This reverts commit 1fdf53ace13f745fe8ad4d2d4e79eed98088d555, reversing
changes made to e5aef1bbf11412eebd4c242b46adff5301353c30.

I had missed that this caused too much size growth on rcar3_salvator-x.
