I don't understand. It looks like you are talking about the second part
of the comment I made on your RFC patchset, about the Rsvd2CPU feature:

https://www.mail-archive.com/netdev@vger.kernel.org/msg139837.html

Switch reset routines are implemented in this patch in global1.c as
mv88e6185_g1_reset and mv88e6352_g1_reset.

6185 and 6352 are implementation references for other switches.

Thanks,

        Vivien
