imx: imx8mm: Add support for Kontron Electronics SL/BL i.MX8M-Mini boards (N801x)
The Kontron SoM-Line i.MX8MM (N801x) by Kontron Electronics GmbH is a SoM
module with an i.MX8M-Mini SoC, 1/2/4 GB LPDDR4 RAM, SPI NOR, eMMC and PMIC.
The matching evaluation boards (Board-Line) have 2 Ethernets, USB 2.0, HDMI/LVDS,
SD card, CAN, RS485 and much more.
