[PATCH 1/2] [ARM] Introduce 'struct machine_class' for SoC level abstraction

Hi Eric,

For machine class (mostly equivalent to SoC) level abstraction.

Could you detail your intended usage of machine_class and how this will fit in 
with the mdesc? Will the mdesc fields override the machine_class fields, or is 
this intended to be a replacement?

Cheers,


Jeremy
