[PATCH 0/3] unify efi debug output across architectures

efi didn't use to have much in the way of kernel command line options,
until some point last year. Then once the efi= option was added, it has
been expanded on.

x86 had an efi=debug option added, but that would be a useful thing
across all efi architectures.

arm64 efi support (predating efi=debug) came with its own 'uefi_debug'
option, and passed along a special verbosity flag when calling into
some not-strictly-arch-specific functions in core efi code.

So:
- Move efi=debug into core code, to be usable by all architectures
- Change arm64 efi code to use 'efi=debug' instead of 'uefi_debug'
- Rework arm64 interface to core code to drop special verbosity flag

Leif Lindholm (3):
  efi/x86: move efi=debug option parsing to core
  arm64: use core efi=debug instead of uefi_debug command line parameter
  efi/arm64: clean up efi_get_fdt_params() interface
