* kern/powerpc/ieee1275/init.c: Rename HEAP_LIMIT to HEAP_MAX_ADDR, and make it easier to figure out. Add HEAP_MIN_SIZE and HEAP_MAX_ADDR definitions. (grub_claim_heap): Use HEAP_MAX_ADDR rather than taking a parameter. Do not avoid claiming a region above HEAP_MAX_ADDR if that would leave us with less than HEAP_MIN_SIZE total heap. Avoid our total amount of heap to surpass HEAP_MAX_SIZE.
