Author: weongyo Date: Tue Apr 20 21:24:32 2010 New Revision: 206927 URL: http://svn.freebsd.org/changeset/base/206927 Log: MFC r201978: Merge from projects/mips to head by hand: Merge the siba bus device. This was moved from mips to dev because siba bus can be in other architectures, like ARM. MFC r202056: Move this to the right location. Grump. MFC r202057: This was somehow copied to the wrong place :(. Remove the spare copy.
