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)...
