Author: marius Date: Sat May 26 09:05:45 2012 New Revision: 236081 URL: http://svn.freebsd.org/changeset/base/236081 Log: MFC: r234291, r234292 Add support for the Atmel SAM9XE family of microcontrollers, which consist of a ARM926EJ-S processor core with up to 512 Kbytes of on-chip flash. Tested with SAM9XE512.
