The MNT Reform 2 is a modular DIY laptop. In its initial version it is based on the BoundaryDevices i.MX8MQ SoM. Some parts have been lifted from BoundaryDevices official U-Boot downstream project.
The device tree has not yet been merged into mainline Linux, but it's already available as v4 on the Linux ARM Kernel Architecture mailing list, which hopefully will now be merged as is.
This U-Boot patchset supports the serial console, the SD card and eMMC, and Gigabit Ethernet.
Best regards, Patrick
