u-boot.git/lib/efi, branch v2023.01

Rename CONFIG_SYS_TEXT_BASE to CONFIG_TEXT_BASE

2022-10-31T15:01:31+00:00

The current name is inconsistent with SPL which uses CONFIG_SPL_TEXT_BASE
and this makes it imposible to use CONFIG_VAL().

Rename it to resolve this problem.

lib: fix selection of CONFIG_CHARSET

2022-05-03T19:39:22+00:00

lib/charset.c is not optional for
EFI_APP || EFI_LOADER || UFS || UT_UNICODE.
These must select CONFIG_CHARSET.

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

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.

efi: Check for failure when initing the app

2021-12-31T05:50:40+00:00

The stub checks for failure with efi_init(). Add this for the app as well.
It is unlikely that anything can be done, but we may as well stop.

efi: Share struct efi_priv between the app and stub code

2021-12-31T05:45:01+00:00

At present each of these has its own static variable and helper functions.
Move them into a shared file.
