Re: Sid: Is there a bus selector component?

[Dave Brolley <brolley at redhat dot com>]

After some thought, it looks like I could do this with two of the 
existing bus-bux components:

connect-pin control selector -> mux1 switch
connect-pin control selector -> mux2 switch

connect-bus master1 bus mux1 upstream
connect-bus master2 bus mux2 upstream

connect-bus mux1 downstream1 slave read-write-port
# don't connect mux1 downstream2 to anything
# don't connect mux2 downstream1 to anything
connect-bus mux2 downstream2 slave read-write-port

Turns out that bux-mux returns sid::bus::unmapped if the selected 
accessor is not connected.

Any objections if I punt on the new selector component and just do this?
