The desired location for FLASH memory will be at 0x0400_0000. This is the address space to which I link U-Boot.
That's OK. It will simply limit your SDRAM size to 64M.
And my cause other problems as well. Don't do it. Map flash at a high address.
Just to be explicit: you _must_ map your flash _well_above_ 0xC000_0000 (the start of the linux kernel area) if you want to run linux.
Since _you_ control BR0 (don't listen to them hardware engineers), you can put it anywhere you want. 0xFF00_0000 is a good spot. 0xFFF0_0000 is not as good of a spot because it limits you to 16MB of flash. Think big. ;-)
