Yes it's ok and I am not using btrfs, I preferred to not modify what I
found.

Aha, is this supposed to fix the boot hang with CONFIG_XHCI_HCD=y? At
the moment I left that disabled in the mox.config provided here. If it
fixes that issue, it is worth picking up your FDT fixup done in the
boot.scr. But what about the mainline DTS file for MOX, can't you just
fix that directly?

I am just using it as my home office switch, with a number of other
boards connected to it. I literally need a single init script which sets
up the bridging domains and VLAN domains that my boards need, and that's
about it. I was also planning to involve it in some 1588/TSN testing
with the other boards though.
