Hello All,
I'm having a problem booting a linux kernel built with Marvell buildroot-sdk-6.0 for an Armada XP development board (DB-78460-BP). The kernel messages indicate that the machine id is not recognized or not supported, but I believe this is because the available machine support is all junk.

Please check your kernel config and/or bootloader.
These are the machine types in my kernel config which should be showing up in the available machine support, but for some reason is garbled.

It looks like the DB-78460-BP board is identifying itself as 0x00000bdc = 3036, which corresponds to the armada_xp_db.
Does anyone have any suggestions on how to debug the cause of the garbling?
Thanks,
Dallas
