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,
