This is the initial series to support Engicam MicroGEA STM32MP1
SoM and it's associated carrier board dts(i) support.
MicroGEA STM32MP1 is an EDIMM SoM based on STM32MP157A from Engicam.
MicroGEA STM32MP1 needs to mount on top of Engicam carrier boards for
creating complete platform boards.
Possible carrier boards are,
- MicroDev 2.0
- MicroDev 7" Open Frame.
Any inputs?
Jagan.
