I pulled u-boot-testing/arm-reloc-and-cache-support and had to clobber
the old branch cause I forgot that it was a rebased branch, so don't
have the old series against which to perform any comparisons, sorry.

Tested 046be127bbccfafe8b84c656ed87e1873e8a63d4 of
git://git.denx.de/u-boot-testing.git with da850evm_config.

The board did not come up. I set a breakpoint in relocate_code and got
a register dump as requested in previous email threads.

(gdb) hbreak relocate_code
Hardware assisted breakpoint 1 at 0xc1080088: file start.S, line 218.
(gdb) c
Continuing.

Breakpoint 1, relocate_code () at start.S:219
