The following series of patches provides implementation of the
kexec_file_load() system call form the arm architecture. zImage and uImage
(legacy format) files are supported. Like on arm64, there is no
possibility of loading a new DTB and the currently loaded is reused.

Changes in v2:
  - add CONFIG_KEXEC_FILE_UIMAGE for optional uImage support
  - MALLOC_SIZE as a define instead of a symbol
  - DCSZ tag holds combined dynamic memory requirements (bss+stack+malloc)
  - use union for a single tag structure
  - copyright notice includes Russell King

Łukasz Stelmach (5):
  arm: decompressor: set malloc pool size for the decompressor
  arm: add image header definitions
  arm: decompressor: define a new zImage tag
  arm: Add kexec_image_info
  arm: kexec_file: load zImage or uImage, initrd and dtb
