efi_loader: Cleanup UEFI Variables menu selection

2025-09-27T07:22:00+00:00

There are 3 options listed between choice/endchoice FILE/TEE/NO_STORE.
There is no reason to add other config with dependencies between
choice/endchoice because they can never be selected because they depends on
only that 3 options which can be selected.
That's why move additional configuration with dependency below choice
section.

efi: Select also CMD_DHCP from EFI_HTTP_BOOT

2025-08-30T18:45:33+00:00

This is needed because distro_efi_read_bootflow_net will then need
dhcp_run which is not already enabled by CMD_NET.

efi_loader: Make EFI_VARIABLES_PRESEED depend on !COMPILE_TEST

2025-08-30T18:45:33+00:00

When doing compile testing build we cannot rely on having a valid file
for EFI_VAR_SEED_FILE to exist, so disable this option when doing
compile tests.

efi_loader: add missing check in FMP.GetImageInfo()

2025-07-26T05:37:03+00:00

The UEFI 2.11 specification, chapter 23.1.3 requires
EFI_FIRMWARE_MANAGEMENT_PROTOCOL.GetImageInfo() to return
EFI_INVALID_PARAMETER if *ImageInfoSize is not too small
and ImageInfo is NULL.

efi_loader: correct EFI_DEBUG_TABLE_ENTRY_SIZE

2025-07-26T05:37:03+00:00

With the current code we allocate to little memory when adding entries to
the EFI_DEBUG_INFO_TABLE and we fail to correctly move entries when an
entry is removed.

EFI_DEBUG_TABLE_ENTRY_SIZE must be the size of an entry in the
EFI_DEBUG_INFO_TABLE, not the size of a pointer.

efi: Create a new CONFIG_EFI

2025-07-26T05:34:31+00:00

Create a Kconfig which indicates that EFI functionality is in use,
either as a client (EFI app / stub) or provider (EFI loader). This will
make it easier to share code between these two parts of U-Boot

efi: Rename the lib/efi directory

2025-07-26T05:29:31+00:00

This directory was created when U-Boot gained the ability to run as an
EFI app in 2015. Since then the EFI-loader feature has been added.

The code in lib/efi is not actually used by the loader, so the name is
confusing.

Rename the directory to efi_client to indicate that it includes files
just for U-Boot being a client of EFI, i.e. the EFI app and stub.

efi_loader: add dbginfodump.efi

2025-07-03T09:26:45+00:00

Provide a test application to dump the EFI_DEBUG_IMAGE_INFO_TABLE
as implemented in EDK II.

EFI_DEBUG_IMAGE_INFO is not packed in contrast to many other EFI
structures.

As of today EDK II when removing an entry in the EfiDebugImageInfoTable
just sets NormalImage = NULL but does not compact the array. So
TableSize reflects the number of non-NULL entries and not the array
size as reported independently in
https://github.com/tianocore/edk2/pull/11013 and
https://github.com/tianocore/edk2/pull/11019.

The current implementation tolerates this deviation from the UEFI
specification.

This is what the output may look like:
