New Revision: 227724
URL: http://svn.freebsd.org/changeset/base/227724
Log:
Fixup cache flush definitions for XLP
mco_icache_sync_range was earlier set to mipsNN_icache_sync_range_index_32
which is not necessary, revert this.
Also, the data cache is coherent so write back is not really needed. This
change is experimental.
