NAK. As expected, this breaks big endian systems like PowerPC.
Tested on AMCC "katmai" board (PPC440SPe):
before (current master):
U-Boot 2013.01-rc2-00174-ge56cdd7 (Jan 03 2013 - 12:41:58)
...
=> fatls ace 0 mnt-xsa
./
../
1250875 kernel.img
19071970 ramdisk.img
2 file(s), 2 dir(s)
After your patch applied:
U-Boot 2013.01-rc2-00174-ge56cdd7-dirty (Jan 03 2013 - 13:01:27)
...
=> fatls ace 0 mnt-xsa
**** ACE CompactFlash not found.
** Bad device size - ace 0 **
So clear NAK.
Best regards,
Wolfgang Denk
