I still don't know why we need both SOC_FAMILY and MACHINE_CLASS in the
first place. MACHINE_CLASS has been around for much longer and if you
look how it's being used or intended to use, you see that there are
hardly any processor differences in the members of those classes (e.g.
openezx, qualcomm msm7, om-gta01/02, clamshell zaurus models, ...).

I'm still unconvinced that we need both variables.
