	Hi all,

This patch series adds generic support for parsing DT properties related
to crash dump kernels ("linux,elfcorehdr" and "linux,elfcorehdr" under
the "/chosen" node), makes use of it on arm32, and performs a few
cleanups.  It is an evolution of the combination of [1] and [2].

The DT bits look fine to me. How do you expect this to be merged? I'm 
happy to take it if arch maintainers can ack it.

The series consists of 6 parts:
  1. Patch 1 prepares architecture-specific code (needed for MIPS only)
     to avoid duplicating elf core header reservation later.
  2. Patch 2 prepares the visibility of variables used to hold
     information retrieved from the DT properties.
  3. Patches 3-5 add support to the FDT core for handling the
     properties.
     This can co-exist safely with architecture-specific handling, until
     the latter has been removed.

Looks like patch 5 doesn't have any dependencies with the series?

  4. Patch 6 removes the non-standard handling of "linux,elfcorehdr" on
     riscv.

I thought this should be applied for 5.14?

  5. Patches 7-8 convert arm64 to use the generic handling instead of
     its own implementation.
  6. Patch 9 adds support for kdump properties to arm32.
     The corresponding patch for kexec-tools is "[PATCH] arm: kdump: Add
     DT properties to crash dump kernel's DTB"[3], which is still valid.

This one can be applied on its own, right?
