Dear Albert ARIBAUD,

Remember: this patch only applies to boards which boot from NOR FLASH! You can test it on other types of boards (NAND-based, etc) for regression testing, but nothing more.
Assuming the NAND loder does not load U-Boot to it's final location at the upper end of RAM, but - say - somewhere in lower memory, the standard relocation preocess will be running, so I think there should be no real difference between (such) NAND booting systems and NOR booting ones - or am I missing something?
FWIW I think you are right. If u-boot is linked for the address where the NAND loader put it, everything should work fine. It can size memory, move a copy of u-boot to the top of memory, and branch to the entry point that continues initialization.
