Hi Joe,

Actually I just commented on a similar patch from Samsung the other
day, and I think we should make a more general decision about these:

I would rather see only one Kconfig option per SoC family and use
ARCH_MEDIATEK without any MACH_* options. We can have other options
for e.g. networking chips from Mediatek that are not closely related
but I would group all the phone and tablet chips under one option
here. Same for the other vendors of course.

Any other opinions?
