I done some work that might help, I used the uClinux-Coldfire source as the
basis for my port of uClinux to the Isicad Prisma (an old CAD workstation) and
I have ported Microwindows to the same platform. There is a set of diffs
against the 0.88 release on my web site, get "mwin-0.88.diff.gz" at:
http://dspace.dial.pipex.com/town/way/fr30/uclinux/downloads/contents.shtml
The changes add a section in Arch.rules for my cross-compiler and modify the
Makefiles for the demo programs to add an ELF to FLAT conversion after the
link stage. There were also a couple of places where I had to replace alloca()
with malloc() because the uClinux libc doesn't have alloca().
The main area that my patches don't cover is the framebuffer interface, the
Prisma needed a custom screen driver so my config excludes all the framebuffer
drivers.

George
