It should (I don't have the latest vanilla just now). And using /proc/mtd it could be identified. > > Kernel makes no guarantee of partition order. It depends on order of > > evaluation.

It seems that kernel does not guarantee order of devices. The order changed even for CF slots: In 2.6.26 internal slot was listed first. Now external slot is listed first. The same problem affects keyboard (kernel with CE-RH2 remote support enumerates touchscreen differently. > How do other boards with NOR and NAND do? Modern devices use OneNAND or similar and don't need any PROM. With a single MTD, numbers are stable. But this is critical problem only for boot. In the user space, there is a lot of chances to prevent it (udev, mount by ID). > Imho we should respect the factory layout and keep kernel in mtd1. Note: I sent a patch to the kernel that fixes PROM layout and introduces two partitions in PROM: Boot PROM System and EN-JP DB3. So it would not be possible. Either mtd0 or mtd2.
