Check that you disabled the cache with 'dcache off' before the 'go'
command (if the cache was enabled). I'm not sure what the address
should be, but given that it gets that far, it is probably fine. As a
rule of thumb, load it low in memory - it will relocate to high in
memory.

OK. I will break out my Beaglebone also, perhaps this week. I really
want to get these patches applied so it works smoothly on TI
platforms.
