oh yeah. Be aware that on v3 we return from car to the main code, so the stack has to be preserved. We may want to move the CAR area to a real memory area as we did on V3. But is this possible?
In theory, it should work. In practice, at least some SimNow version choked on the patches I had which moved the CAR area. I shall dig them up again and have someone check them on real hardware. Of course it is possible that my patches were faulty. To be honest, I have the feeling I forgot to change some other code which references the old location.
Yes, DCACHE_RAM_BASE is referenced when the sys_info structure is copied from cache to ram, and a couple of other places. So you need to also fix up the mainboard Option.lb
