Merge tag 'remoteproc-for-3.6' of git://git.kernel.org/pub/scm/linux/kernel/git/ohad/remoteproc

Pull remoteproc update from Ohad Ben-Cohen:
 - custom binary format support from Sjur Brændeland
 - groundwork for recovery and runtime pm support
 - some cleanups and API simplifications

Fix up conflicts in drivers/remoteproc/remoteproc_core.c due to clashes
with earlier cleanups by Sjur Brændeland (with part of the cleanups
moved into the new remoteproc_elf_loader.c file).

* tag 'remoteproc-for-3.6' of git://git.kernel.org/pub/scm/linux/kernel/git/ohad/remoteproc:
  MAINTAINERS: add remoteproc's git
  remoteproc: Support custom firmware handlers
  remoteproc: Move Elf related functions to separate file
  remoteproc: Add function rproc_get_boot_addr
  remoteproc: Pass struct fw to load_segments and find_rsc_table.
  remoteproc: adopt the driver core's alloc/add/del/put naming
  remoteproc: remove the get_by_name/put API
  remoteproc: support non-iommu carveout assignment
  remoteproc: simplify unregister/free interfaces
  remoteproc: remove the now-redundant kref
  remoteproc: maintain a generic child device for each rproc
  remoteproc: allocate vrings on demand, free when not needed
