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.

Tested booting Debian with a 6.1.x linux kernel on a mnt/reform2 using
nvme rootfs and microsd /boot. Some oddities with video and wifi that do
not occur with the vendor u-boot, but seems like huge progress.
The patch still applies to master; could this be considered for merging
soon?
I've also verified that the patch not only builds, but actually boots,
based on git commit c9c2c95d4cd27fe0cd41fe13a863899d268f973c (and also
works on v2023.04, for good measure)...

Thanks, I apply it and CI is running, if no issues are found it will
part of my next PR.
