Oops, sorry. Fixed in v2.

Due to distribution differences [1][2], I see =y built-in as the default
on mobile platforms and =m modular as the default on server platforms.

But thinking about it, we could get a poweroff, reset, over-temperature,
or other interrupt before we get to the initramfs. So the pin controller
driver should be =y built-in.

One might make rootfs media =y built-in to make testing easier, but I
prefer to put my rootfs on SATA, as SD/MMC is much slower and smaller by
comparison.

Thanks,
