As I have no real understanding of the differences between V3 and V4 firmware,
I only follow the V3
specs at http://bcm-specs.sipsolutions.net. My usage of the V4 specs is to
checking if they can
clean a point of confusion in the V3 spec. The radio version check is
eliminated at the beginning of
the phy_initb5 routine in http://bcm-specs.sipsolutions.net/B5PHY. As there are
radio version checks
later in the routine, I think it was meant to be removed here.

See step 2 of http://bcm-specs.sipsolutions.net/B5PHY.

As I said earlier, everything came from http://bcm-specs.sipsolutions.net.
