My apologies for the delayed reply.  I've been on vacation and unplugged 
by design.

Currently, we are booting out of the nor_flash partition and also 
loading the kernel from there.  Due to other technical challenges, we 
are not using either the mtd1 or mtd2 partitions at the moment.

dev:    size   erasesize  name
mtd0: 00400000 00000200 "nor_flash"
mtd1: 00100000 00020000 "nand.bootloader"
mtd2: 00300000 00020000 "nand.kernel"
mtd3: 1fc00000 00020000 "nand.rootfs"

Please see my thread "UBIFS corruption after software upgrade" 
originally posted on 7/24/2012 for more details about the problem that 
prompted this question about erase block size.  Any assistance you can 
provide with this issue would be greatly appreciated.

Best regards,
