Even on 32bit systems a full 4GB of DRAM may be installed and reported by the DRAM controller. Whether these 4GB are larger available depends on the size/configuration of address decoding windows and architectural features.
This increases the fields holding the RAM size to have at least 33bits (i.e. we use a u64) and fixes the fallout from the change: some casts, the usage of min() and a few printf formats have to be adjusted.
