When a need raise up to use JTAG interface for system's devices

For such purpose, usually the user layer

connection to vendor hardware.
This method is slow and not generic.
 
We propose to implement general JTAG interface and infrastructure
to communicate with user layer application. In such way, we can
have the standard JTAG interface core part and separation from
specific HW implementation.
This allow new capability to debug the CPU or program system's 
device via BMC without additional devices nor cost. 

Hi Oleksandr

Do you have patches for OpenOCD? Or maybe i should ask it another way,
what user space tools are you using?

Thanks
