		User can config it based on hardware design. For ESP32-D2WD chip,

	---help---
		The PSRAM CS IO can be any unused GPIO, user can config it based on
		hardware design.
		For ESP32-PICO chip, the psram share clock with flash, so user do
		not need to configure the clock IO.

config ESP32_SPIRAM_SPIWP_SD3_PIN
	int "SPI PSRAM WP(SD3) Pin when customising pins via eFuse (read help)"
	range 0 33
	default 7
	---help---
		This value is ignored unless flash mode is set to DIO or DOUT and
		the SPI flash pins have been overridden by setting the eFuses
		SPI_PAD_CONFIG_xxx.

		When this is the case, the eFuse config only defines 3 of the 4
		Quad I/O data pins. The WP pin (aka ESP32 pin "SD_DATA_3" or SPI
		flash pin "IO2") is not specified in eFuse. And the psram only
		has QPI mode, the WP pin is necessary, so we need to configure
		this value here.

		When flash mode is set to QIO or QOUT, the PSRAM WP pin will be
		set as the value configured in bootloader.

		For ESP32-PICO chip, the default value of this config should be 7.
