[PATCH 0/7] arm: add UEFI support

[Leif Lindholm]

This set adds support for UEFI platforms 32-bit ARM platforms,
consisting of:
- UEFI stub support
  Turns the kernel into a UEFI executable, able to launch without a
  dedicated bootloader.
- UEFI runtime services
  Lets the kernel interact with services provided by firmware.
  (Used by 'efibootmgr' application.)
- UEFI system descriptions
  For now, adds the ability to extract information about available
  RAM from UEFI rather than hard-wired in .dtb or on command line.

This set depends on:
- Ard Biesheuvel "efi: efistub: Convert into static library"
                 About to go into linux-next, aiming for 3.17.
- Mark Salter    "arm: use generic fixmap.h"
- Mark Salter    "arm: add early_ioremap support"

The bits shared with arm64 went into 3.16-rc1.

Changes from previous version:
- Stub and runtime services support now merged (like on arm64) - they
  are no longer functionally separable.
- Some fixes and cleanup.

Leif Lindholm (4):
  arm: break part of __soft_restart out into separate function
  arm: add new asm macro update_sctlr
  arm: efi: use strcmp instead of strncmp for fdt parsing
  init: efi: arm: enable (U)EFI runtime services on arm

Roy Franz (3):
  arm: add strstr to compressed string.c
  arm: Disable stack protection for decompressor/stub
  arm: add [U]EFI support
