Hi Chris/All,
The attached patch adds support for the IDT Interprise processor RC32438
based on the MIPS 4KC core.
Additional information regarding IDT processor's can be found at

Hi Chris,
Appreciate your feedback.
Please see my comments below, inline prefixed by [rkt]
Look forward for additional comments/suggestions, if any.
Thanks
Rakesh

Additional comments:
* Firstly, it's really great to see this!
* A single 1.6MB patch is far from ideal, please try to break it
into a series of smaller logically separate patches. It's hard to
comment on a giant patch. Perhaps something like:
- a patch for each CPU
- a patch for each driver
- a patch for each platform/eval-board
and see what you have left. Each patch should have a suitable
description. Also put "Signed-off-by:" lines on your patches.
[rkt] Agreed, 1.6MB is a huge patch. I will try to break it down into
multiple patches (ard 5) based on platform/eval board and will
send it out soon.
* You shouldn't be removing .gitignore :-)
[rkt] I think these are still there.
* The Ethernet drivers should probably go jeff@xxxxxxxxxx and cc
netdev@xxxxxxxxxxxxxxx
[rkt] The Ethernet interface/driver is integral to each processor
and dependent upon other system header files, unlike a regular NIC.
I can try posting the patches (probably sub-patch) to Jeff and netdev,
in order to get feedback on the driver.
* The code contains unreferenced functions? Without even looking
hard I can see rc32434_mii_handler is declared and not used for
example.
[rkt] Chris you hit the bulls eye. This is the only function which
I missed out... Will clean it up.
* It might be that some of the CPU-level code should be platform
level. For example having two UARTs is a feature of the EB434 not
the rc32434 so EB434_UART1_IRQ is misplaced I would argue.
[rkt] Since all the IDT's processors are primarily SoC's, the UARTS are
part of the processor. In case on rc32434 there is only 1 UART. However
rc32438 has 2 UARTS
* Some init code should probably be declared __init and similar
* There is quite a bit of extraneous white-space that could be
cleaned up and some minor indentation cleanups to match what is
elsewhere in the kernel.
[rkt] Will try to clean up as much as possible...
Sorry this is a little vague and 'hand-wavy', if you post smaller logically complete patches I think you'll get better feedback where people can comment more easily. Ideally inline to the email if you can, m$ lookout/$exchange as that just makes a mess, if you have to use that then attach them as you did.
