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. * You shouldn't be removing .gitignore :-) * The Ethernet drivers should probably go jeff@xxxxxxxxxx and cc netdev@xxxxxxxxxxxxxxx * The code contains unreferenced functions? Without even looking hard I can see rc32434_mii_handler is declared and not used for example. * 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. * 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. 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.
