I don't believe we'll be using the BCMA infrastructure going forward.
We'll be doing our own MDIO Phys, adding them to the device tree, and
referencing them through the DT/OF method.  This is the current plan
for NSP, NS2, Cygnus, and other upcoming platforms.  If someone can
find an elegant way of splitting off the Phy code from the BCMA core,
then this can be better than it is now.  But, it will take someone
with docs, time, and hardware to give this code the audit and cleanup
it really needs.  BTW, my last comment isn't intended as a slight
against the authors of this code.  It is unfortunate that they were
put in a position of having to reverse engineer drivers for this HW.

Thanks,
Jon
