SMC interfaced memory and Cache – how design works A memory connected to SMC
can be accessed directly from the system memory space: 0x6000_000. This is the
typical way to access the asynchronous memory. However, accessing these
locations will not utilize cache. In order to use cache, one must access
0x1900_000, the locations otherwise being called as MEMY region. User only has
to ensure few things for above to work:
1) Always compile/link the code against MEMY (0x1900_000) locations.
2) Make sure that M4P_MEMY register is programmed as 0x60000003 (default).
3) Program/load the compiled code in to 0x6000_000, the system memory
4) Access 0x1900_0000 directly. Processor will take care of reading from
