Gabe Black (gabeblack@chromium.org) just uploaded a new patch set to gerrit, which you can find at http://review.coreboot.org/3574 -gerrit commit 6ebf6b43eae273555db13a7684dae82d616a76d4 Author: Gabe Black <gabeblack@chromium.org> Date: Sat Jun 29 22:55:15 2013 -0700 am335x: Fix the address of the pinmux registers. The pinmux register data structure describes a subset of the control module registers, but the address which pointed to the base of the pinmux registers was actually being set to the beginning of all the cotrnol module registers, not just those having to do with the pinmux. With this address fixed, the UART now works on the beaglebone black.
