I do not understand what is the point of adding dm6467.h without
#ifdef CONFIG_ARCH_DAVINCI_DM646x. If I have 6446 why should I add
6467. This make sense if I have board with multiple chips like dm6446
chip and dm6467 chips. Can you please explain.

I can understand you are trying to follow omap model but some other
nice models are also available for example SH model we can take
advantage of those.

I like this approach in SH that they are growing in multiple-direction
as they added supports for cpus, boards and drivers. They did their
porting in such a way that it is easy to add more boards and more cpus
by just copying paste and change your settings as per your hardware.

Currently we are assuming 6446 chip as common. I think 6446 part
should also come in ifdef CONFIG_ARCH_DAVINCI_DM646x. If I am using
DM355 why should I need 6446.

And Currently arch-davinci is based only on TI EVM board. There are
different kinds of boards available in market. To add them in linux
tree we should move current EVM to CONFIG_MACH_DAVINCI_TIEVM. So I
think we also need to revise our directory sturcture to grow our
family.

I am also CCing to LKML and Paul Mundt to get feedbacks.

Sudhakar, why you are using space key, I think you should use tab key
for spacing.

Thank you,

Jaswinder Singh.
