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.

include: export uuid.h

Move this header to include/u-boot/ so that it can be used by external
tools.

efi: Avoid using dm_scan_other()

2024-01-13T17:17:46+00:00

This function is defined by bootstd so using it precludes using that
feature. Use the board_early_init_r() feature instead.

Nove the affected code into a new file, so that it is clear that
this relates to board init.

lib: Remove inclusion from these files

2023-12-21T13:54:37+00:00

After some header file cleanups to add missing include files, remove
common.h from all files in the lib directory. This primarily means just
dropping the line but in a few cases we need to add in other header
files now.

efi: fix devpath_is_partition()

2022-04-29T12:25:39+00:00

If the path consists only of an end node, it does not refer to a partition.
Avoid returning a random value from the stack in this case.

doc: replace @return by Return:

2022-01-19T17:11:34+00:00

Sphinx expects Return: and not @return to indicate a return value.

find . -name '*.c' -exec \
sed -i 's/^\(\s\)\*\(\s*\)@return\(\s\)/\1*\2Return:\3/' {} \;

find . -name '*.h' -exec \

efi: Support the efi command in the app

2022-01-15T09:57:22+00:00

At present the 'efi' command only works in the EFI payload. Update it to
work in the app too, so the memory map can be examined.

efi: Move exit_boot_services into a function

2022-01-15T09:57:22+00:00

At present this code is inline in the app and stub. But they do the same
thing. The difference is that the stub does it immediately and the app
doesn't want to do it until the end (when it boots a kernel) or not at
all, if returning to UEFI.

Move it into a function so it can be called as needed.

Add a comment showing how to store the memory map so that it can be
accessed within the app if needed, for debugging purposes only. The map
can change without notice.
