Hrm, in that case perhaps the first patch is OK to go?  The changes
still being discussed are to the DT binding handling and the addition of
a new parsing mechanism (for MPIDR, which I'd do as a separate patch).
This would be quite helpful, tweaks to the first patch typically cause
manual rebases against the DT patches which increases the stop energy.

Catalin seemed very concerned about any use at all of MPIDR, that's why
the code was removed originally.  Catalin?
