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: stub: Change _debug_uart_putc function to inline

2025-06-06T09:12:20+00:00

Update definition of _debug_uart_putc to static inline.
This will allow to avoid compilation warnings about unused code
after introduction of patch changing debug uart functions to
dummies if CONFIG_DEBUG_UART is not set.
This also matches the instructions in include/debug_uart.h and
provides consistency with implementations for other platforms.

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.

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.

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: 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: 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.

serial: Update NS16550_t and struct NS16550

2021-01-05T19:24:40+00:00

Typedefs should not be used in U-Boot and structs should be lower case.
Update the code to use struct ns16550 consistently.

Put a header guard on the file while we are here.

dm: core: Create a new header file for 'compat' features

2020-02-06T02:33:46+00:00

At present dm/device.h includes the linux-compatible features. This
requires including linux/compat.h which in turn includes a lot of headers.
One of these is malloc.h which we thus end up including in every file in
U-Boot. Apart from the inefficiency of this, it is problematic for sandbox
which needs to use the system malloc() in some files.

Move the compatibility features into a separate header file.
