I could be convinced that this is the right thing to do, but I want to
really make sure that it has had sufficient testing. Specifically as
this patch is written we'll be updating the drive strength for all
boards. Increasing the drive strength can sometimes introduce new
problems (reflections, noise, ...) so we have to be confident that
we're not breaking someone that used to work by increasing the drive
strength here. How much has this been tested?

From further discussion internally, it sounds as if this should be
fine and fixes more than just this one eMMC part. Thus:

We've been running with this patch in the Chrome OS kernel. If it
looks OK to you, it'd be great for it to land in your tree. Thanks!
