Hi Robin,

Thanks for reviewing the patch.

I like your idea of having a single kernel which can boot on any board
and also agree with you that code duplication is not a good thing.

However, based on our customer's feedback so far, we prefer to keep it separate
for each board, so that code doesn't get to messy or people don't have to
look at unwanted code.

Also since IDT's processors are SoC's and do undergo various rev's for the chips,
in which certain feature (hardware) are fixed/removed/added. In this case having
a separate directory (at the cost of code duplication) is easier to maintain.

I'm not Ralf, but I gave your patch a quick once-over anyway for the hell of it.

I see a lot of duplicated code, esp in arch/mips/idt-boards and the network drivers.

Is it possible to have a kernel capable of booting on all IDT boards? Could such a kernel detect what board it's actually running on - or enough elements of the board configuration to provide more generic drivers?
