This driver adds a basic console that uses the arm JTAG
DCC to transfer data back and forth. It has support for

This console is created under the HVC driver, and should be named
/dev/hvcX (or /dev/hvc0 for example).

this DCC driver implements "one channel", but what about implementing
"multiple channels". For example reserve few(3) bits for channel number,
and two bits for carried data, then fill the rest bytes with with some data
and send the word(32 bits) over DCC. On the Linux side writing on /dev/hvcX
puts the number X as channel number, and on the other side the CPU
emulator gets the data and redistribute it to TCP/IP socket.
I have started write some code implementing this. Are there any one
interested
in this multiple channels, and are there any one started to work on it?

Asen
