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.

I had hoped you could take the series...

My current thought is I'll take 2-5, 7 and 8 given that's what I have
acks for and the others can be applied independently.

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?

Indeed. So you can take it independently.

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

I thought this should be applied for 5.14?

Me too, but unfortunately that hasn't happened yet...

Buried in the middle of this series is not going to encourage it to be
picked up as a fix.
