[RFC PATCH 00/11] Affirm SMMU coherent pagetable walker capability on RPMh SoCs

[Konrad Dybcio]

I only read back the SMMU config on X1E & 7280, but I have it on good
authority that this concerns all RPMh SoCs. Sending as RFC just in case.

Lacking coherency can hurt performance, but claiming coherency where it's
absent would lead to a kaboom.
