[PATCH v4 0/7] prepare Protonic board code for mainline

[Oleksij Rempel]

changes v4:
- follow suggestion provided by Ahmad and open-code the root node
  registration and call it machine.of
- board: rename crc and cs
- board: ignore most of init related errors. Even if one part will fail,
  we should be able to get as mach as possible.

changes v3:
- remove barebox-serial driver and use read the rfid directy from board
  code (as was done in initial implementation)
- use initcall instead of registering driver in the board code
- add delayed USB scan
- add rampoops node
- add partition tables 

changes v2:
- add power init support for KvG boards
- spell fixes
- do not print error on probe exit
- add of_console_get_by_alias() helper
- free requested gpio array
- exit fec init only in case of PROBE_DEFERED

This patch series is a preparation and actual Protonic board code.
Following changes was made in the main code:
- register DT root node as device to make it possible to loade board
  code as usual driver
- provide helpers to read ethernet mac from nvmem cell register in a
  devicetree.
- provide barebox-serial driver which should be a nvmem cell consumer
  and
  serial-number DT property provider.
- provide gpio helper to read gpio based board revision.


Oleksij Rempel (7):
  of: base: register DT root as device
  gpiolib: add gpio_array_to_id helper to get ID out of GPIO array
  common: console_common: add of_console_get_by_alias() helper
  of: of_device_get_match_compatible() helper
  ARM: protonic-imx6: port Protonic specific board code
  ARM: dts: unify barebox and barebox,env partitions for all Protonic
    boards
  ARM: dts: imx6q-prti6q: add pstore/ramoops node
