[PATCH 00/22] arm/arm64: UEFI stubs + runtime services

[Leif Lindholm <leif.lindholm@linaro.org>]

This is a combined set of patches for the arm and arm64 kernel
support for UEFI firmware.

The set depends on the following prerequisite sets:
- Laura Abbott's 'Remove ARM meminfo'
- Matt Fleming's 'Move facility flags to struct efi'
- Mark Salter's  'Generic fixmap'
- Mark Salter's  'Generic early_ioremap'
- Mark Salter's  'EFI memory map iteration helper'

All of these are held on top of 3.14-rc1, with the patches in this set,
in git://git.linaro.org/people/leif.lindholm/linux.git, rebasing branch
uefi-for-upstream.

New in this version:
- Much more stub code shared arm/arm64.
- Stub looks in configuration tables for DT.
- Stub creates empty DT if none found/specified.
- Stub ignores dtb= option when UEFI Secure Boot active.
- Stub deletes any memory nodes in DT.
- Kernel sets up available RAM for memblock from UEFI memory map.
  (So no longer need different DTs or command line parameters for
   otherwise identical platforms with different amounts of RAM.)
- arm64 now compatible with 64K pages (with 4K UEFI page size).
- Fix mapping of runtime mmio regions on arm64.
- Reworked update_sctlr asm macro.
- Various cleanup and style fixes.
