I have been going through the code and I have stumbled accross a file called
sc520_car.S that has something called Cache as ram. I am guessing that this is
something special for the sc520 correct? Why was there a need to do this? Why
was the Cache used like ram in the boot process?
Also I am I see something called early_board_init. I trace this to a file
called eNET.S but all it does is jumps back to where it came from. I don't
understand.
Where is the external memory controller set up at?
thanks for your time
