Well, I would like to use it. I started working on my own mpc750 hal, but
after doing a few files I noticed that the ppc60x hal would run on the
mpc750 for all the files I have worked on so far (just the header files).
The only changes I had to make were the cache sizes and associativities. I
haven't gone through all the files yet, but maybe a slightly modified
ppc60x hal will work for me.
Can anyone tell me if there is a difference between ppc603 and mpc603?
Can I use your port or should I finish the one I started? Why isn't yours
in the cvs repository?

I would like to do a powermac platform. I'm a grad student and I am
looking for a neat platform to do research with. I'm thinking the powermac
would be nice because I like powerpc, I already own 2 new world powermacs,
and I can use the keyboard and display for instrumentation even without a
remote gdb connection.
Also I'm sort of looking for an excuse to do a port so I can learn
something.
