rright.  the bit that's missing is a link to
ConfigMemoryPortInterface.  there will be a similar one for I-Cache
but let's deal with that later.

for the Minerva case, ConfigMemoryPortInterface actually establishes
(instantiates) the entire actual instance.  it *should* be
instantiating Loadtore1 (because that is derived from
PortInterfaceBase).

etc.

i think we have a way forward.
