Hello,

This patchset adds initial board support for iMX8QXP AI_ML board
from Einfochips. This board is one of the Consumer Edition and AI
boards of the 96Boards family.

This initial supports contains following peripherals which are tested and
known to work:

1. Debug serial via UART2
2. SD card
3. Ethernet

Below is the boot log from SPL to Linux kernel:
