New Revision: 192531
URL: http://svn.freebsd.org/changeset/base/192531
Log:
Skip interleaved RAM target on MPC85xx during renitialization of the local
access windows. This eliminates hangs on systems which are configured to use
interleaved mode: prior to this fix we were simply cutting ourselves from
access to the main memory in this case.
