I have no information what the target for your new processor might be;
there is such systems that go to basically a single big customer / a
single, highly specific use case, and there are those that are
intended for general use - the more use cases the better.  If you want
to make your system easy to use for a big grouyp of people, then make
sure that standard debug tools work.  Include JTAG, and make sure it
works with standard tools like the Abatron BDI2000/3000, Lauterbach
Trace32 and OpenOCD etc.

Well, without a working binut=ils you cannot build U-Boot anyway, so
you probably have to wait for that.

BedBug is strill there, because it was useful for some (at some point
of time), and it does not hurt to have it.  I think the actual number
of users is epsilon.

I'd recommend to save the efforts, and rather help the guys who are
working on binutils.  This is probably better invested time, then.

Best regards,
