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.
