As someone else mentioned, there is a limit to the amount of cachable memory
onboard. If your L2 cache has 8 bit tag rams, then the cached memory size is:
<cache size> * (2 ^ <tag size>).
With 256K L2 cache, this is 64M. With 512K cache, this is 128M.
Any memory about these limits will not be cached. You DON'T want to use this
memory.
