efi_loader: export efi_ecpt_guid

2026-03-14T07:10:26+00:00

Export the ECPT GUID, to prepare accessing it from more than one location.

The C file containing the GUID is compiled only when CONFIG_EFI_ECPT is
set; gate the export accordingly.

efi_loader: fix ecpt size computation

2026-02-15T07:30:57+00:00

The size of the memory allocated for the EFI Conformance Profiles Table is
computed with `num_entries' always equal to zero, which is incorrect when
CONFIG_EFI_EBBR_2_1_CONFORMANCE is enabled.

This can be verified by allocating the ECPT memory with malloc() instead of
efi_allocate_pool(), building u-boot with sandbox_defconfig and
CONFIG_VALGRIND=y, and by finally running the following command:

  valgrind --suppressions=scripts/u-boot.supp \
    ./u-boot -T -c 'efidebug tables'

Fix this by using an array of the supported profiles GUIDs instead, which
should also be easier to extend in the future as U-Boot should publish the
GUIDs for all supported EBBR revisions.

We largely do not need  in these files, so drop it. The only
exception here is that efi_freestanding.c needs  and had

efi: adjust ebbr to v2.1 in conformance profile

2022-12-17T13:37:33+00:00

The EFI Conformance Profile Table entry for EBBR appears in v2.1.0 of the
EBBR specification[1]. Update naming accordingly.

While at it, update the EBBR version referenced in the documentation.

efi: Create ECPT table

2022-09-03T07:35:48+00:00

The ECPT table will be included in the UEFI specification 2.9+.
The ECPT table was introduced in UEFI following the code-first path. The
acceptance ticket can be viewed at:
	https://bugzilla.tianocore.org/show_bug.cgi?id=3591

The Conformance Profiles table is a UEFI configuration table that contains
GUID of the UEFI profiles that the UEFI implementation conforms with.

The ECPT table is created when CONFIG_EFI_ECPT=y.
The config is set by default.
