A little tip that I found useful - if you modify the CCR initialisation to
use part of the cache as memory mapped RAM, you can use this area for the
IPL's stack and variable storage - then you can use the debugger to test the
presence of the SDRAM in area 2 or 3 without having to reflash all the time.
