Hi

Graham Gower started working on JZ4730 support based on this series some
time ago, but had to put a hold on it because he was busy with other
things. You both should probably get in contact.

There are some parts on the JZ4730 which are similar those on the
JZ4740, others are different. So to put support for common parts into a
shared source directory is the right approach. But I think this is
something that can be done when somebody actually steps forward to
implement support for a different JZ47xx SoC. Luckily the code is not
set into stone and can be re-factored or renamed once it is required or
makes sense to do.
Another issue with naming is that while a component might be similar in
JZ4730 and JZ4740 it might be completely different in a different JZ47xx
SoC. So naming a driver 'jz47xx_driver' instead of 'jz4740_driver' wont
work either.
