Author: andrew Date: Sat Aug 17 18:51:38 2013 New Revision: 254461 URL: http://svnweb.freebsd.org/changeset/base/254461 Log: Rename device vfp to option VFP and retire the ARM_VFP_SUPPORT option. This simplifies enabling as previously both options were required to be enabled, now we only need a single option. While here enable VFP on the PandaBoard.
