New Revision: 256753
URL: http://svnweb.freebsd.org/changeset/base/256753
Log:
MFP4: 1136252
Add an option ATSE_CFI_HACK to allow memory mapped CFI devices to have
their address range allocated sharable so that atse(4) can find it's
Ethernet address in the expected location.
We intend to remove this hack once the BERI platform has a loader.
