Over 16 MBytes space on flash mentioned above can be only used for ``data saving``, like file system.
Mapping data/instructions to 32-bit physical address space (so as to be accessed by the CPU) needs the support of MMU. However {IDF_TARGET_NAME} doesn't support this feature. Only ESP32-S3 supports this up to now.

OPI Flash Support
-----------------
This feature is only supporetd on ESP32-S3 for now.
This feature is only supported on ESP32-S3 for now.
OPI flash means that the flash chip supports octal peripheral interface, which has octal I/O pins. Different octal flash has different configurations and different commands. Hence, it is necessary to carefully check the support list.
