Well, you made a lot of changes. I think you use 2009.08 from Freescale
tree, and there are a lot of differences with mainline tree.

Maybe it is worth if you check your code with the boars already
supported by U-Boot mainline having the i.MX53 SOC (Freescale's
mx53-loco, -ard, and -smd for example).

Try to add a #define DEBUG in the code, for example to understand if
something is alive before the relocation.

I am afraid that it is too difficult, because it depends on your custom
hardware. Next step should be to attach a JTAG debugger to see what is
happening.
