I think we can start by moving the stuff step by step into the phone,
if anyone wants to work on this, it would be much appreciated.
Layer2 (LAPDm) should be relatively simple, but starting from RR/MM/CC
and the cell reselection I expect some more difficulties...

One thing to keep in mind for anyone trying that is that you can't do
unaligned access ...
and we do plenty of them ...
So either you need to fix that in the code, or catch the exception, and
emulate the access ...

Fixing the unaligned accesses should be cross-platform, right? So this kind
of thing can be done at a measured pace even while the code still runs
PC-side.
Not being a GCC expert, is there some way to find out where these problem
accesses are?

Much to read. I think about getting a e-reader for all those
datasheets and specifications.

Note arm7tdmi is very different from arm-v7. Many arm7tdmi don't have
much of a mmu. Calypso might though.

Thank you for pointing this out. As far as i read the datasheet
i couldnt find any traces of a mmu, besides the mentioning
that it per default has none but you can order one if you like to.

Experts will excuse me, but can anyone explain quickly what would be the
advantages of moving the layer2 into the phone?

It's just a step towards running it entirely on the phone ...
But if your interest in osmocom is mainly as a research tool (like it is
for me), then there is no advantage.
