[PATCH v2 0/3] RISC-V: Add kexec/kdump support​

[Nick Kossifidis]

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. The patch is still
a work in progress but a draft version can be found at:

http://riscv.ics.forth.gr/kexec-tools.patch

v2:
 * Re-base on newer kernel tree and minor cleanups
 * Properly populate the ioresources tree, 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
