We're trying to move to a more modular build of multi_v7_defconfig.
Please make all drivers that are not required for booting '=m',
and ensure that they have a MODULE_DEVICE_TABLE entry that allows
autoloading.

Most of the symbols are already marked =m here, but there are a
few that I'm wondering about:

-rc3 is fine, we can easily handle the conflicts when merging in your

seems non-essential.

What are these required for? I assume you need them for MMC? If so, that's
fine.
