Hi Jocke,
The patch was done precisely for it. You can copy a U-Boot image from an 
address in flash to another and calculate the new pointers in the GOT an 
FIXUP sections before do the copy.
But you need another change in U-Boot to turn it fully relocatable. 
U-Boot is hardly joined with the link address TEXT_BASE. You must 
replace it for a label in U-Boot and change the lines in the U-Boot code 
where there is a direct or indirect reference (as CFG_MONITOR_BASE) to 
TEXT_BASE.

Best regards,
Txema
