Dmitry refers to non-groundbreaking features, such as USB or SD Card
which are a 5 minute job to enable (since the SoC bits are in place),
mostly just requiring confirming with schematics that regulator
assignment hasn't changed versus other reference boards..

Please keep in mind that the more fragmented your changes are, the
longer it will take for them to be accepted upstream, as separate
patches carry a lot of overhead compared to what they offer.
