This patch series adds kexec/kdump and crash kernel
support on RISC-V. For testing the patches a patched
version of kexec-tools is needed (still a work in
progress) which can be found at:

https://riscv.ics.forth.gr/kexec-tools-patched.tar.xz

v3:
 * Rebase on newer kernel tree
 * Minor cleanups
 * Split UAPI changes to a separate patch
 * Improve / cleanup init_resources
 * Resolve Palmer's comments

v2:
 * Rebase on newer kernel tree
 * Minor cleanups
 * Properly populate the ioresources tre, so that it
   can be used later on for implementing strict /dev/mem
 * Use linux,usable-memory on /memory instead of a new binding
 * USe a reserved-memory node for ELF core header

Nick Kossifidis (5):
  RISC-V: Add EM_RISCV to kexec UAPI header
  RISC-V: Add kexec support
  RISC-V: Improve init_resources
  RISC-V: Add kdump support
  RISC-V: Add crash kernel support
