It works on ALL systems for which a working port of U-boot exists.

Remember that without the BDI attached U-Boot will  have  to  perform
all  required  initialization anyway - so which initialization should
be needed for the BDI? Only these which  are  caused  by  the  slower
speed  over  the  JTAG port (disable watchdogs) or dealing with debug

I agree that this is not a trivial task.

This just means that your port of U-Boot is still broken.
