I'd much prefer the former actually - it's already hard enough to use
the config tools with the kernel due to the number of silly options
being presented, there's no need to make it worse.

In fact, I'd like to see more of the former (provided done sensibly)
to reduce the number of config options seen for configurations to cut
down on the shere noise of useless options.  For example, if I've
decided I don't want to support TI OMAP platforms, then I shouldn't
be offered the TI OMAP MMC driver.
