I set up the 8xx/82xx CPM. I can cheat here and grab some physical
pages of memory before the VM grabs them and makes me jump through
hoops to get pages I can just __pa() or __va() :-). I could probably
move this to later. I also use a #define IMMR for a pointer to the
internal space of the processor. Saves a few cycles, but I should
really make this a variable. I can use the #define because I know
the VM mapping is going to be 1:1.
It's nothing I can't change......
