PATCH v3 1/5 efi/arm64: Avoid EFI_ERROR as a generic return code

Quoted 26 lines · Ard Biesheuvel

As EFI_ERROR is not a UEFI result code but a local invention only intended to allow get_dram_base() to signal failure, we should not use it elsewhere.

Replace with EFI_LOAD_ERROR.

PATCH v3 4/5 efi: efistub: refactor stub components

In order to move from the #include "../../../xxxxx.c" anti-pattern used by both the x86 and arm64 versions of the stub to a static library linked into either the kernel proper (arm64) or a separate boot executable (x86), there is some prepatory work required.

This patch does the following:
- move forward declarations of functions shared between the arch specific and the generic parts of the stub to include/linux/efi.h
- move forward declarations of functions shared between various .c files of the generic stub code to a new local header file called "efistub.h"
- add #includes to all .c files which were formerly relying on the #includor to include the correct header files
- remove all static modifiers from functions which will need to be externally visible once we move to a static library

PATCH v3 5/5 efi: efistub: convert into static library

This patch changes both x86 and arm64 efistub implementations from #including shared .c files under drivers/firmware/efi to building the shared code as a static library.

The x86 code uses a stub built into the boot executable which uncompresses the kernel at boot time. In this case, the library is linked into the decompressor.

In the arm64 case, the stub is part of the kernel proper so the library is linked into the kernel proper as well.
