Okay, I verified that; it's definitely correct.

I get to decompress_kernel() now IF I comment out the mcr
instruction in cache_on that writes to the MMU control register. After a
pause (but no messages from decompress_kernel) execution does get to
head-armv.S. But it stops again in __ret when the MMU is turned on.

R5 is 0xc0008000 going in, looks right.
At this point I'm ready to believe we do have a memory timing
problem. Or maybe it's the A0-step cpu, although I couldn't find anything
obvious in the SA-1110 errata for these early chips.
Thanks for the help so far!
