Subject: [PATCH 0/5] kexec_file_load() for arm

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.

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
