Subject: [PATCH 0/3] Introduce mini-dump support for remoteproc.

Sometimes firmware sizes can be in ten's of MB's and reading
all the memory during coredump can consume lot of time and
memory.
Introducing support for mini-dumps. Mini-dump contains smallest
amount of useful information, that could help to debug subsystem
crashes.
During bootup memory is allocated in SMEM (Shared memory)
in the form of a table that contains the physical
addresses and sizes of the regions that are supposed to be
collected during coredump. This memory is shared amongst all
processors in a Qualcomm platform, so all remoteprocs
fill in their entry in the global table once they are out
of reset.
This patch series adds support for parsing the global minidump
table and uses the current coredump frameork to expose this memory
to userspace during remoteproc's recovery.

This patch series also integrates the patch:
