Alternatively it might be work adding gdb stubs into LinuxBIOS. And doing using a remote debugger that way. What a jtag interface provides is really not much more than what gdb stubs provides. At least not after memory is initialized.
that's not quite correct. There are a host of cpu failures you can detect with a jtag interface that gdb stubs are useless for. GDB stubs requires that the processor be basically sane, jtag interfaces are not near as picky.
