Hi Øyvind. You might want to ask the OpenOCD list about this. I've used the DCC as an end user before for sending printf() style messages and RPC over and it's quite good for that.
I'm not sure how your proposal would work though. My understanding is that the DCC is only accessible over JTAG and, if you already have a JTAG connection, then you might as well use that to debug.

Hi all,
I was wondering someone knows about a ARM DCC (debug communications channel) device driver.
The idea is to run gdbserver on /dev/dcc such that application debugging does not hog a serial/ethernet port.
I'd modify OpenOCD to forward the DCC onto a TCP/IP port to connect GDB to the gdbserver.
