You can chose any setting you like. It's just that low boot is
usually the most efficient and flexible one, as it allows to put the
U-Boot code at the begin of the flash memory with room to grow after
it, so you don't have any nasty gaps and it's trivial to change flash
device sizes.

See previous postings. And no, TQM uses 0x4000.0000, not 0x0400.0000.
