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.
