I have written a kernel linux kernel driver, a library and a monitor-like
debugger (flash programming, stepping, breakpoints, memory modify etc.).
The target I am using is a custom made 5204 board, but I have the 
5206 eval board and it works as the 5204 target - there are no
differences in respect to BDM.
I am using binutils 2.8.1 and cygnus cdk 18 beta with patches for
coldfire by Rod Barman. I do not know how good coldfire support in the
egcs project's source tree is, but I will check out soon.
Using this environment I was able to port our tasking kernel to 
coldfire. Debugging is assembly level only, this sucks
So my next task is going to be modifying the QUICC bdm gdb-target
to use my coldfire bdm abstraction library...

So: BDM support ---- done
    as, ld etc. ---- done
    cc          ---- done
    gdb         ---- still missing

I have the schematics and GAL equations for a BDM adapter compatible
to P&E's. The hardware is very cheap... and can be built by almost anybody.

Since this is a work in progress, I have not uploaded the BDM driver and
library anywhere. If there is need maybe somebody is willing to
provide some space on her ftp server, and I will upload it there.

If there is only very limited need I can cope with sending the BDM package
out by email.

kind regards,
Rolf
