Sure, I'll be happy to split this off. I should've thought to split
it up before sending. Thanks for the suggestion.

IIUC, my original default works, as we have used it frequently in
other places in the kernel.
grep -rI "default ARCH_BCM_IPROC" * | wc -l
15

However, if the above is preferred (or the other 15 massively broken),
I'll be happy to do it that way.

Naa, just trying to be more concise, while adding the NSP products to
the list.. BCM47094 is a type of BCM4709. So, it is still there :)
