In my tests, I found that the window at 0x20000000 is bigger than
documented in the datasheet. I'm not entirely sure about how it is
routed in the hardware, maybe I need to add a 64M offset to account for
the re-map, but I did run memtester for a while with the biggest memory
size I could use, and it did not print any errors.

Since I use only 256M low-mem, the long-jump is not necessary.
