Well, it is called "gdbserver" and requires running code to work.  You 
might be able to put gdbserver into Flash and have it download your 
program-under-test into SRAM?  gdbserver would need you to write some 
small code to use the serial port on the Target system.  The current gdb 
would have the driver needed.

IIRC, gdbserver is most effective on the X86 CPUs as they have internal 
debug registers (breakpoint) accessible from software. You cannot use it 
like a jtag unit where it will debug programs in flash or to program 
flash. 

I don't know much more about it, try searching the archives of uClinux. 
It was used on some of the processors without MMUs or JTAG like the 
Motorola ColdFire / 68EZ328.
