Author: imp Date: Sat Mar 20 03:39:35 2010 New Revision: 205354 URL: http://svn.freebsd.org/changeset/base/205354
Log: Add support for the Samsung S3C2xx0 family of ARM SoCs written by Andrew Turner. The kernel supports the LN2410SBC evaluation board, and likely others. These parts (or similar ones) are in some open hardware designs for phones.
