      efi: efistub: Convert into static library · f4f75ad5
      Ard Biesheuvel authored
      This patch changes both x86 and arm64 efistub implementations
      from #including shared .c files under drivers/firmware/efi to
      building 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.

      efi: split efisubsystem from efivars · a9499fa7
      Tom Gundersen authored
      This registers /sys/firmware/efi/{,systab,efivars/} whenever EFI is enabled
      and the system is booted with EFI.
      
      This allows
       *) userspace to check for the existence of /sys/firmware/efi as a way
          to determine whether or it is running on an EFI system.
       *) 'mount -t efivarfs none /sys/firmware/efi/efivars' without manually
          loading any modules.
      
      [ Also, move the efivar API into vars.c and unconditionally compile it.
        This allows us to move efivars.c, which now only contains the sysfs
        variable code, into the firmware/efi directory. Note that the efivars.c
        filename is kept to maintain backwards compatability with the old
        efivars.ko module. With this patch it is now possible for efivarfs
        to be built without CONFIG_EFI_VARS - Matt ]

      efivars: Move pstore code into the new EFI directory · 04851772
      Matt Fleming authored
      efivars.c has grown far too large and needs to be divided up. Create a
      new directory and move the persistence storage code to efi-pstore.c now
      that it uses the new efivar API. This helps us to greatly reduce the
      size of efivars.c and paves the way for moving other code out of
      efivars.c.
      
      Note that because CONFIG_EFI_VARS can be built as a module efi-pstore
      must also include support for building as a module.
