Yes, I think I will eventually get around to it. For now the focus is on getting the Linux kernel support into shape for upstream, however. As I needed a convenient way to boot Linux on the device for this task a Barebox port was the logical first step. ;) It may take a while until I circle back to improve the Barebox support. > > The MNT Reform is a DIY Laptop, built around a Boundarydevices i.MX8MQ SoM. > > This adds a pretty minimal support, as there is no upstream DT yet.
