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.
Marvell>> bootm 0x2000000
## Booting kernel from Legacy Image at 02000000 ...
Image Name: linux-3.0
Created: 2012-08-02 14:04:49 UTC
Image Type: ARM Linux Kernel Image (uncompressed)
Data Size: 3303200 Bytes = 3.2 MB
Load Address: 02008000
Entry Point: 02008000

Error: unrecognized/unsupported machine ID (r1 = 0x00000bdc).
Available machine support:

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
