MMIO classes

[Martin Stein]

Hi Aditya,

Nice to hear that you like the MMIO framework :-) Personally, I can't
see a benefit in constructing an object of a class that does nothing
else than inheriting from an Mmio::Register. When trying to compile your
example, my compiler complains that I can't use 'ob' in the constant
expression 'write<...>', which sounds reasonable to me. Why do you think
that 'Register_array' isn't what you're looking for? It may be helpful
if you could explain your use case more precisely.

Cheers,
Martin
