Oh, so the only change here relative to Tegra30 is that the final memory
range is larger; the others don't move around at all. Is that all that
patch 4/6 is trying to cope with? If so, I'd suggest simplifying that
patch a bunch; perhaps just remove the final if() check in each function
and make all accesses with (offs > 0x200) go to smmu->regs[2]?
You can always add checks to probe() that memory range 0 and 1 have the
expected size such that the code in smmu_{read,write} will work as expected.
