* Routine: get_board_revision
* Description: Detect if we are running on a Beagle revision Ax/Bx,
- * C1/2/3, or C4. This can be done by reading
+ * C1/2/3, C4 or xM. This can be done by reading
* the level of GPIO173, GPIO172 and GPIO171. This should
* result in
* GPIO173, GPIO172, GPIO171: 1 1 1 => Ax/Bx
* GPIO173, GPIO172, GPIO171: 1 1 0 => C1/2/3
* GPIO173, GPIO172, GPIO171: 1 0 1 => C4
+ * GPIO173, GPIO172, GPIO171: 0 0 0 => xM
