Due to some design decision, the internal PHY on Broadcom BCM7xxx chips is not entirely self contained and does not report its internal revision through MII_PHYSID2, that is left to external PHY designs. This forces us to get the PHY revision from the GENET and SF2 switch drivers because those two peripherals integrate such a PHY and do contain the PHY revision in their registers. The approach taken here is hopefully easy to extend to similar needs for other chips/ as well. Thanks!
