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.
