New Revision: 254171
URL: http://svnweb.freebsd.org/changeset/base/254171
Log:
- The address lies in the bus space handle, not in the cookie
- Use the right address when calling kva_free()
(Is there any reason why the s3c2xx0 comes with its own version of bs_map/
bs_unmap ? It seems to be just the same as in bus_space_generic.c)
