How to identify ARM board programmatically

Question

Is there a way how to programmatically identify which arm board I'm currently running on? Either raspberry pi, cubieboard, or beagleboneblack? These 3 types are enough to differentiate. I was hoping to use cat /sys/devices/virtual/dmi/id/sys_vendor but this is not available on ARM ports of debian :-/

Answer 1

You can read the MIDR register which will provide implementer, variant, architecutre, partnum, and revision that you might help to distinguish the boards on which you're running your code.

You can get that register using MRC p15, 0, <Rt>, c0, c0, 0
