bringup via USB stick storage

One more runmbing thought;

Well-configured U-Boot should allow to operate IDE disk and/or
USB stick storage.  This means self contained USB storage can
do network-less NetBSD installation.  NAS U-Boot may, however,
have no provision of such the functionality since it's not designed
as a general computer.  I'm considering about the design trade-
off to add LIBSA USB storage which means I'm about to enter the
forbidden territory of USB wonders without help of interrupt
handlers.
