	  This config option helps decide whether flash is Quad or Octal, but please note some limitations:

	  1. If the flash chip is an Octal one, even if one of "QIO", "QOUT", "DIO", "DOUT" options is
	      selected in `ESPTOOLPY_FLASHMODE`, our code will automatically change the
	      mode to "OPI" and the sample mode will be STR.
	  2. If the flash chip is a Quad one, even if "OPI" is selected in `ESPTOOLPY_FLASHMODE`, our code will
	     automatically change the mode to "DIO".
	  3. Please do not rely on this option when you are pretty sure that you are using Octal flash,
	     please enable `ESPTOOLPY_OCT_FLASH` option, then you can choose `DTR` sample mode
	     in `ESPTOOLPY_FLASH_SAMPLE_MODE`. Otherwise, only `STR` mode is available.
	  4. Enabling this feature reduces available internal RAM size (around 900 bytes).
	     If your IRAM space is insufficient and you're aware of your flash type,
	     disable this option and select corresponding flash type options.
