Seems reasonable. Be aware of register arguments in locore being used 
differently by the various firmware. I think I dealt with this OK, let 
me know if I missed something.

I sent a mail to the gxemul maintainer and he was happy to incorporate 
my patches for the YAMON sysreqs which real YAMON implementations 
implement for this stuff.

CFE is a far more complete firmware than PMON and is generally more 
helpful to kernel hackers than PMON is.
Sadly I haven't had any more free time to work on Sentry5 since 
April/May. I have chip docs, but still haven't quite got the PCI bus 
enumeration right.

Cheers...
