only makes sense in kernelspace / uboot due to the mmu, but thats where
you need it. userspace is mostly better debugged with a gdb running on
the device.

the software used on the host side is openocd which gives you a console
to the jtag (halting, stepping, etc) and a gdb stub to connect gdb on
the host to.

for more informations please take a look at this page

the debug board is pin-compatible with the amontec jtagkey tiny, just
with different usb-ids

the essential config is:
ft2232_vid_pid 0x1457 0x5118
ft2232_layout "jtagkey"
