Here's my version of the changes required, following the ideas I've put
forward in previous threads.  Build tested, but not boot tested yet.
They're queued for my nightly build and boot test this evening.

The final patch in the series is experimental as it's missing the
detection to make use of the ZTE UART bits.  Also, I'm debating whether
we should make that conditional on a config symbol so that non-ZTE
platforms don't have to suffer the consequences of the conditional 32-bit
