Firmware-Assisted Dump (FADump) is currently supported only on pseries
platform. This patch series adds support for powernv platform too. 

The first two patches refactor the FADump code to make use of common
code across multiple platforms. The third patch adds basic FADump support
to powernv platform. The next patch processes state data provided by f/w
and adds core notes to core file. The last patch adds support to export
opalcore. This is to make debugging of failures in opal code easier.

The patch series is tested with a few workarounds in firmware and kernel
as the full and final firmware support is currently being worked on.
The below skiboot patch series adds the relevant OPAL changes:
