If you have system RAM accessible by the CPU but not used by Linux
in normal operation, you can give the physical address at which the
available RAM starts, and the MTDRAM driver will use it instead of
allocating space from Linux's available memory. Otherwise, leave
allocating space from Linux's available memory. Otherwise, leave
this set to zero. Most people will want to leave this as zero.
