there were a whole bunch of changes from 1.0.0 to 1.1.1 -- I took the
opportunity to clean up Gordon's original code. There aren't really a
whole lot of timing-sensitive areas in the u-boot code. If you let it
run w/out single-stepping in JTAG, what happens? Just hangs? While
it's hung, what happens if you then take a look using JTAG to see what
it's doing? Could you dissassemble a few instructions around the PC
where it's hanging? If so, then it should be easy to figure out where
in u-boot it's sticking, using arm-linux-objdump -S u-boot on the
u-boot which hasn't had all its symbols removed.
