Well, someone needs to look into those issues and find the solutions. I
can certainly cook some patches, but I don't have a hardware platform
to test things on. If you're willing to do some testing+debugging, then
we could try to work together on this.

But I'd like first to hear about the status of Gustavo's work, as I'd
prefer to avoid duplicating his work.

Most likely from uClinux-dist, which has been for a while the reference
Linux distribution for noMMU platforms. Unfortunately, it is no longer
that well maintained.

Best regards,
