Edge Compute Module 0 Carrier is an industrial form factor evaluation
board from Edgeble AI.
General features:

microSD slot
2x MIPI CSI2 connectors
MIPI DSI connector
2x USB Host
1x USB OTG
Ethernet
mini PCIe
Onboard PoE
RS485, RS232, CAN
Micro Phone array
Speaker
RTC battery slot
40-pin expansion

Edge Compute Module 0 needs to mount on top of this Carrier board for
creating Edge Compute Module 0 Carrier platform.
Add support for it.
