efi: Rename END to EFI_DP_END

2025-05-25T09:27:18+00:00

This exported symbol has a very generic name. Rename it to indicate that
it relates to EFI and device-paths.

Fix checkpatch warnings related to use of multiple assignments.

efi_loader: Separate device path into its own header

2025-05-25T09:27:18+00:00

These functions are useful for the EFI app. As a first step towards
making these available outside lib/efi_loader, create a separate header
file and include it where needed. Add proper comments to the functions,
since many are missing at present.

efi_loader: allow concatenation with contained end node

2024-06-10T09:43:36+00:00

Allow appending a device-path to a device-path that contains an end node
as separator. We need this feature for creating boot options specifying
kernel, initrd, and dtb.

efi_loader: Clean up efi_dp_append and efi_dp_concat

2024-01-13T17:17:47+00:00

Looking back at the initrd storing functionality, we introduced three
functions, efi_dp_append_or_concatenate(), efi_dp_append/concat(). In
hindsight we could have simplified that by a lot. First of all none of
the functions append anything. They all allocate a new device path and
concatenate the contents of two device paths in one. A boolean parameter
controls the final device path -- if that's true an end node is injected
between the two device paths.

So let's rewrite this and make it a bit easier to read. Get rid of
efi_dp_append(), efi_dp_concat() and rename
efi_dp_append_or_concatenate() to efi_dp_concat(). This is far more
intuitive and the only adjustment that is needed is an extra boolean
argument on all callsites.

efi_loader: Remove

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

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

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

SPDX: Convert a few files that were missed before

2018-05-11T00:38:35+00:00

As part of the main conversion a few files were missed.  These files had
additional whitespace after the '*' and before the SPDX tag and my
previous regex was too strict.  This time I did a grep for all SPDX tags
and then filtered out anything that matched the correct styles.
