I thought I'd explained that already, haven't I? At power-up a ROM code 
at FFFF0000 (64KB of ROM taking precedence over CS0, as seen from JTAG) 
does a few checks then jumps to FFF90000, which is the NOR Flash. The 
U-boot image is mapped and flashed so that the entry point is at 
FFF90000. The entry point then does further inits (some under condition 
that SKIP_CONFIG_LOWLEVEL_INIT is not defined), initializes RAM, 
relocates code to TEXT_BASE (if CONFIG_SKIP_RELOCATE_UBOOT is not 
defined) and then jumps to it.

Amicalement,
