About finding the bsp for qemu ( t2080rdb)

I've tried all variants IIRC of qoriq (e550/e5500/e6500) in qemu
sometime ago (5.x development branch) and it booted but then was blocked
on the serial port interaction and I really had no idea how to fix that.
Debugger points out to the function where RTEMS asked serial port about
a status and this was blocking forever. Look at this thread for more
information: https://www.mail-archive.com/users@rtems.org/msg02543.html

IMHO having qoriq bsp running in qemu would be better than qemuppc as
qemuppc is IIRC about ppc750 which is quite old and is being replaced by
qoriq variant last I checked. Speaking solely about BEA's RAD750 ->
RAD5500 update here.

So just compile bsp and try it in qemu and see for yourself, perhaps you
will be more lucky and get that running well...

Good luck!
