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 Signed-off-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Signed-off-by: Matt Fleming <matt.fleming@intel.com>
