We'll expand the support for beagleboard peripherals post 1.0. Marking this as an enhancement and leaving the milestone blank. 12267 2 bruce.ashfield 2011-03-03 17:59:40 +0000 bumping to 1.1 15451 3 jingdong.lu 2011-08-14 20:14:57 +0000 commit dcfb6e4d2ab5df32f0f2408a1aafd6923018555f Author: Bruce Ashfield <bruce.ashfield@windriver.com> Date: Wed Jun 8 15:33:02 2011 -0400 15453 4 yi.zhao 2011-08-14 23:01:18 +0000 Verified with 20110806 build.
