Mike Frysinger	e82b762f29	Blackfin: fix jtag console tstc The jtag tstc operation was checking the hardware to see if data is available from it (which is fine for the jtag getc operation), but the higher layers need to know whether any data is available. Since we have to read up to 4 bytes at a time from the hardware, the higher layers need to know they can consume the cached bytes as well.

The jtag tstc operation was checking the hardware to see if data is
available from it (which is fine for the jtag getc operation), but the
higher layers need to know whether any data is available.  Since we have
to read up to 4 bytes at a time from the hardware, the higher layers need
to know they can consume the cached bytes as well.

Blackfin: support console-over-JTAG

The Blackfin JTAG has the ability to pass data via a back-channel without
halting the processor.  Utilize that channel to emulate a console.
