[RFC PATCH 0/7] provide ELF/KEXEC support for MIPS ath79 and malta

[Oleksij Rempel]

This patch set is a squashed and rebased patch set of work done by:
Antony Pavlov and Yegor Yefremov.

This code suppose provide kernel start support for some MIPS machines.
For example ath79 (Atheros) and malta should be able to work with it.

So far only kernel and cmdline passing is supported. ARM and other arches would
probably work with some more or less work.

Antony Pavlov (5):
  resource: add create_resource() helper function
  filetype: add ELF type
  bootm: add kexec ELF support
  MIPS: add kexec ELF loading support
  MIPS: malta: enable kexec

Oleksij Rempel (2):
  MIPS: ath79: add kexec support
  MIPS: configs: add KEXEC=y to atheros devices
