have PPC stub wait for ARM #5

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
right now we can only run a ppcboot.elf that does NOT use any of the same 
memory area that 1-512 does. (Linux does not overlap ... BootMii does)

This is because when the bootROM gets done with the 1-512's memory area, it 
executes our patched code immediately and there's no time AFTER that to load a 
ppcboot file SO we've had to load if BEFORE the race attack.

We need to figure out a simple way of having PPC wait for ARM to flag it that 
the ppcboot.elf file is loaded so it can proceed to jump to it's entry point.
