Seconded.  The criteria should generally be whether the code interacts
with the subsystem (as opposed to some isolated register poking to "turn
on" a common logic block), with a fair bit of deference to the
developer/maintainer's intuition rather than an unyielding rule (we have
enough of those in u-boot).

And when someone adds a new board, they may find that their
"board-specific" driver code wasn't actually as board-specific as they
thought if something very similar is sitting in the same directory they
need to add it to, as opposed to having 100 copies of it hidden in the
directories of other boards.

Yes.  We should get away from the model of having generic code call *the*
USB/NAND/SATA/whatever driver which is chosen at link time.
