Author: jmallett Date: Wed Apr 21 07:28:57 2010 New Revision: 206986 URL: http://svn.freebsd.org/changeset/base/206986 Log: Move to using the SDK for UART stuff (not thrilled about using RBR for the base or hard-coding 1024 as the offset, but that's what the Simple Executive does. We can abstract this in a *reg.h in the near future at least.)
