[Dario Binacchi]

The series adds support for Engicam MicroGEA boards:

- BMM
- RMM
- GTW

based on MicroGEA-MX6UL SoM.

[PATCH 01/10] dt-bindings: arm: fsl: support Engicam MicroGEA BMM board

[Dario Binacchi]

Add devicetree bindings for Engicam MicroGEA BMM board based on the
Engicam MicroGEA SoM (System-on-Module).

The use of an enum for a single element is justified by the future
addition of other boards based on the same SoM.

00:04:9f is Freescale Semiconductor. Since you are not Freescale, are
you actually allowed to use this MAC address?

If you look around, you find most boards use 00 00 00 00 00 00 as a
place holder, and the bootloader puts in the real per device MAC
address.
