New Revision: 204131
URL: http://svn.freebsd.org/changeset/base/204131
Log:
Cleanups for sys/mips/rmi/bus_space_rmi.c
- remove pci related code from bus_space_rmi.c, we will have another
file for PCI bus space functions which will do byte-swapping.
- remove local SWAP implementation
- added TODO stub for unimplemented functions
