I get your point, but I think U-Boot is somewhat different from linux
here. It might just as well be a architecture custodian or board
maintainer that that takes care of USB device XY. And as Wolfgang
pointed out custodians have to maintain code distributed across
different directories already (see POST layer).

But maybe it would make the upcoming kconfig system more intuitive if a
usb net driver was found under drivers-net instead of drivers-usb?!
