The desired location for FLASH memory will be at 0x0400_0000. This

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.
I didn't know that about Linux... but who says I'm going to run Linux? (OK, I am, just kidding.)
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. ;-)
0xFF00_0000 makes sense to me, and works fine. It fits in with what I've seen in other implementations. As I stated previously, 0x0400_0000 was a purely historical number. I'll take the recommendations of those who have been there before... thanks.
