Well the way the debug_ll code is currenty set up just won't scale.
The basic problem is that the debug_ll code should be machine specific,
not arch specific..
Probably the best long term solution is to set up the debug uart based
on DT data and initialize it in the uncompress code. Anybody debugging
lower level stuff can certainly patch in the ucompress debug_ll code.

Tony
