config SPI_FLASH_VENDOR_MXIC_SUPPORTED
	bool

config SPI_FLASH_SUPPORT_ISSI_CHIP
	bool "ISSI"
	default y
	help
	  Enable this to support auto detection of ISSI chips if chip vendor not directly
	  given by ``chip_drv`` member of the chip struct. This adds support for variant
	  chips, however will extend detecting time.

config SPI_FLASH_SUPPORT_MXIC_CHIP
	bool "MXIC"
	default y
	help
	  Enable this to support auto detection of MXIC chips if chip vendor not directly
	  given by ``chip_drv`` member of the chip struct. This adds support for variant
	  chips, however will extend detecting time.

config SPI_FLASH_SUPPORT_GD_CHIP
	bool "GigaDevice"
	default y
	help
	  Enable this to support auto detection of GD (GigaDevice) chips if chip vendor not
	  directly given by ``chip_drv`` member of the chip struct. If you are using Wrover
	  modules, please don't disable this, otherwise your flash may not work in 4-bit
	  mode.

	  This adds support for variant chips, however will extend detecting time and image
	  size. Note that the default chip driver supports the GD chips with product ID
	  60H.

config SPI_FLASH_SUPPORT_WINBOND_CHIP
	bool "Winbond"
	default y
	help
	  Enable this to support auto detection of Winbond chips if chip vendor not directly
	  given by ``chip_drv`` member of the chip struct. This adds support for variant
	  chips, however will extend detecting time.

config SPI_FLASH_SUPPORT_BOYA_CHIP
	bool "BOYA"
	default y if !SOC_SERIES_ESP32
	help
	  Enable this to support auto detection of BOYA chips if chip vendor not directly
	  given by ``chip_drv`` member of the chip struct. This adds support for variant
	  chips, however will extend detecting time.

config SPI_FLASH_SUPPORT_TH_CHIP
	bool "TH"
	default y if !SOC_SERIES_ESP32
	help
	  Enable this to support auto detection of TH chips if chip vendor not directly
	  given by ``chip_drv`` member of the chip struct. This adds support for variant
	  chips, however will extend detecting time.

	bool "mxic (opi)"
	depends on SOC_SERIES_ESP32S3
	default y
	help
	  Enable this to support auto detection of Octal MXIC chips if chip vendor not directly
	  given by ``chip_drv`` member of the chip struct. This adds support for variant
	  chips, however will extend detecting time.

config SPI_FLASH_ROM_DRIVER_PATCH
	bool "SPI flash ROM driver patched functions"
	default y
	help
	  Enable this flag to use patched versions of SPI flash ROM driver functions.
	  This option should be enabled, if any one of the following is true: (1) need to write
	  to flash on ESP32-D2WD; (2) main SPI flash is connected to non-default pins; (3) main
	  SPI flash chip is manufactured by ISSI.

config BOOTLOADER_FLASH_XMC_SUPPORT
	bool "Support flash chips of XMC (READ HELP FIRST)"
	default y
	help
	  Perform the startup flow recommended by XMC. Please consult XMC for the details of this flow.
	  XMC chips will be forbidden to be used, when this option is disabled.

	  DON'T DISABLE THIS UNLESS YOU KNOW WHAT YOU ARE DOING.

choice BOOTLOADER_VDDSDIO_BOOST
	bool "VDDSDIO LDO voltage"
	default BOOTLOADER_VDDSDIO_BOOST_1_9V
	depends on !SOC_SERIES_ESP32C3
	help
	  If this option is enabled, and VDDSDIO LDO is set to 1.8V (using eFuse
	  or MTDI bootstrapping pin), bootloader will change LDO settings to
	  output 1.9V instead. This helps prevent flash chip from browning out
	  during flash programming operations.

	  This option has no effect if VDDSDIO is set to 3.3V, or if the internal
	  VDDSDIO regulator is disabled via eFuse.

config BOOTLOADER_REGION_PROTECTION_ENABLE
	bool "Protect unmapped memory regions from unintended accesses"
	default y
	help
	  Protects the unmapped memory regions of the entire address space from unintended accesses.
	  This will ensure that an exception will be triggered whenever the CPU performs a memory
	  operation on unmapped regions of the address space.

config SPI_FLASH_HPM_ENABLE

	help
	  The Simple Boot is a method of booting that doesn't depend on a
	  2nd stage bootloader. Please note that some of the bootloader features
	  are not available using simple boot, such secure boot and OTA.
