console driver on software simulator

We're doing the simulation in software (similar to PSIM) so I can do a
"printf" within in the simulator.  I realize I can emulate a UART but I
thought that was more complicated than needed to be.  I'm thinking of a
console driver that just takes it's input and then does printf.
