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.

This U-Boot patchset supports the serial console, the SD card and
eMMC, Gigabit Ethernet and USB.

Changes since v3:
- Adjusted to Binman changes in main branch.
- Cleaned up environment variables akin to i.MX8MM.
- Added vendor-prefix to device tree filename.
- Provided ramdisk_addr_r.
Changes since v2:
- Switched to Binman.
Changes since v1:
- Synced DTS with files in Linux git repo.
- Added support for USB host ports.

Hi,

is there anything I can do to help get attention on this patchset?
I'm now regularly rebasing the patchset and adjusting it to all the
changes that happen in-tree to the other boards to keep the patchset
compiling and working.

Right now I'd have to send a v5 to remove a single define that's now
obsolete and hence breaks compilation, but I'm not sure it's worth
sending it out if there's gonna be a v6 and v7 for another rebase
soon anyway.

Cheers,
Patrick

Not a whole lot, sorry.  The big hold up right now is that Stefano is
out currently and that means a number of imx patches are still
outstanding.

Aside from what I just sent out in reply to Fabio's comment, it probably
makes sense to hold off on reposting until Stefano is back.
