Is your feature request related to a problem?

Since S3 introduced a new Flash type (OPI) it is mandantory to flash the correct
combination of used Flash / PSRAM type bootloader/ firmware. Without the device does fail to boot.
It is a problem for the user to know which flash mode has to be used for Flash / PSRAM.
Since there are many different variants already to get, and it is not possible to identify the used chips and there modes.

Describe the solution you'd like

A command which prints out the supported flash type for S3 for flash and PSRAM

Describe alternatives you've considered

Guessing and trying all variants until S3 is booting.
