am35xx, twister: could not write nand flash

Hello Scott,

I currently tried current U-Boot HEAD

commit fedab338f3459315cb69627fcf46032ec8df1753
Merge: 74b5b5d f6b690e
Author: Wolfgang Denk <wd <at> denx.de>
Date:   Thu Jun 7 23:42:17 2012 +0200

     Merge branch 'master' of git://git.denx.de/u-boot-video

on the twister board, and detected that a "run update" fails with:

twister => run update
SW ECC selected

NAND erase: device 0 offset 0x80000, size 0x100000
Erasing at 0x160000 -- 100% complete.
OK

NAND write:
(board hangs ...)

Environment var:
update=nandecc sw;nand erase ${uboot_addr} 100000;nand write ${loadaddr} ${uboot_addr} 80000

So I started "git bisection":

[hs <at> pollux u-boot]$ git bisect start
[hs <at> pollux u-boot]$ git bisect bad
