Author: imp Date: Sun Jun 18 21:03:48 2017 New Revision: 320082 URL: https://svnweb.freebsd.org/changeset/base/320082 Log: Create a new option ARM_USE_V6_BUSDMA to force an armv4/5 kernel to use the armv6 busdma interface. This interface uses more memory than the armv4 one, but bounces more data more often so may be more correct than the armv4 one. It is intended for debugging purposes only at the moment.
