OMAP3: Beagle: Add board revision detection
With BeagleBoard revision C some HW changes are introduced (e.g. PinMUX) which might need different software handling. For this, GPIO pin 171 (GPIO module 6, offset 11) can be used to check for board revision. If this pin is low, we have a rev C board. Else it must be a revision Ax or Bx board. To handle board differences you can call function beagle_get_revision(). E.g.: if (beagle_get_revision()) { /* do special revision C stuff here */ } Signed-off-by: Dirk Behme <dirk.behme@googlemail.com>
