freebsd/sys/mips/include/ppireg.h
Warner Losh 45d426a34e FreeBSD/mips port. The FreeBSD/mips port targets mips32, mips64,
mips32r2 and mips64r2 (and close relatives) processors.  There
presently is support for ADMtek ADM5120, A mips 4Kc in a malta board,
the RB533 routerboard (based on IDT RC32434) and some preliminary
support for sibtye/broadcom designs.  Other hardware support will be
forthcomcing.

This port boots multiuser under gxemul emulating the malta board and
also bootstraps on the hardware whose support is forthcoming...

Oleksandr Tymoshenko, Wojciech Koszek, Warner Losh, Olivier Houchard,
Randall Stewert and others that have contributed to the mips2 and/or
mips2-jnpr perforce branches.  Juniper contirbuted a generic mips port
late in the life cycle of the misp2 branch.  Warner Losh merged the
mips2 and Juniper code bases, and others list above have worked for
the past several months to get to multiuser.

In addition, the mips2 work owe a debt to the trail blazing efforts of
the original mips branch in perforce done by Juli Mallett.
