This commit adds initial board support for iMX8QXP AI_ML board from Einfochips. This board is one of the 96Boards Consumer Edition and AI boards of the 96Boards family based on i.MX8QXP SoC from NXP/Freescale.
This initial supports contains following peripherals which are tested and known to work:
- Debug serial via UART2
- SD card
- Ethernet
More information about this board can be found in arrow website: https://www.arrow.com/en/products/imx8-ai-ml/arrow-development-tools

Looks like this patch has fallen through the cracks! Let me know if I have to resend it (again).
Your board cannot be built clean - can you rebase and repost ? Thanks !
You can check the reason here:

Best regards, Stefano
Thanks, Mani
