[PATCH 00/10] Add interface to update firmware from Petitboot

[Samuel Mendoza-Jonas]

This series adds a generic framework to a) parse firmware version strings of
both the local machine and a remote metadata file, b) compare them for
differences and if the remote is newer, c) update the machine's firmware
to the remote updated version.
The pointy-end of the update process is provided by platform-specific code.
This series adds platform-powerpc support for updating BMC-machines with
pflash. Other methods of updating (eg. update_flash, etc) can be easily
added to fit into this framework.

A new ncurses screen is added, "Firmware Updates" which allows the user to
set a remote metadata and/or update source, and execute an update. Current
and remote update versions are displayed here for comparison.

By itself this new functionality is recommended for development purposes
only - this does *not* implement authentication or verification of the
remote update. Access to this feature is only enabled if the
"petitboot,platform_update?" parameter is set to true in NVRAM.

Samuel Mendoza-Jonas (10):
  lib/process: Safely read partial stdout buffer

  lib/system: Add pflash
  Explicitly parse version strings read from flash
  lib/version: Version parsing and comparison
  lib/device-tree: Parse package versions from ibm,firmware-versions
  Add generic support for platform updates
  ui/ncurses: "Firmware Updates" screen
  discover/platform-powerpc: Determine ppc platform type
  discover/platform-powerpc: Platform Firmware Updates
