For the romable feature:
We need to save the ram area (there might be initialized variables,
and code-fields...) into rom and copy it back at system startup.
\ save ram area
unlock sramdp @ lock constant ram-start
unlock ramdp @ sramdp @ - lock constant ram-len
ram-start ram-origin ram-len unlock tcmove lock
ram-len allot align
ram-origin ram-start ram-len cmove ;
