config PLATFORM_EC_SPI_FLASH_REGS
	bool "Enable SPI flash registers"
	default y
	help
	  Enables flash registers for SPI flash (both internal and external).
	  When enabled, two new functions will become available: (1) a function
	  to compute the block write protection range from a set of status
	  registers, and (2) the inverse function to set the status registers
	  based on the desired protection offset/length.

config PLATFORM_EC_PROTECTED_STORAGE_OFF
	hex "Position of the RO image in Flash memory"
	default 0x0
	help
	  Sets the position in flash memory where the RO image begins. This is
	  the address that will be used to start copying the image into RAM.

config PLATFORM_EC_PROTECTED_STORAGE_SIZE
	hex "Size of the RO image in Flash memory"
	default 0x40000
	help
	  The total size of the RO image in flash memory. This will dictate the
	  ending position of the RO image being copied into RAM when combined
	  with PLATFORM_EC_PROTECTED_STORAGE_OFF.

config PLATFORM_EC_WRITABLE_STORAGE_OFF
	hex "Position of the RW image in Flash memory"
	default 0x40000
	help
	  Sets the position in flash memory where the RW image begins. This is
	  the address that will be used to start copying the image into RAM.

config PLATFORM_EC_WRITABLE_STORAGE_SIZE
	hex "Size of the RW image in Flash memory"
	default 0x40000
	help
	  The total size of the RW image in flash memory. This will dictate the
	  ending position of the RW image being copied into RAM when combined
	  with PLATFORM_EC_WRITABLE_STORAGE_OFF.

config PLATFORM_EC_CONSOLE_CMD_CHARGEN
	bool "Console command: chargen"
	depends on UART_INTERRUPT_DRIVEN
	help
	  Enables the "chargen" console command, which sends a continuous
	  stream of characters to the EC console.

	  This allows to create tests which validate console output by
	  verifying that no characters in the received sequence were lost.

config PLATFORM_EC_CONSOLE_CMD_FLASH
	bool "Console commands: flasherase, flashread, flashwrite"
	default y
	help
	  Enables various console commands:

	     flasherase - erase flash region
	     flashread - read from flash to memory
	     flashwrite - write memory to flash

config PLATFORM_EC_CONSOLE_CMD_FLASHINFO
	bool "Console commands: flashinfo"
	default y
	help
	  Enables various console commands:

	     flashinfo - displays information about the flash storage

config PLATFORM_EC_CONSOLE_CMD_FLASH_WP
	bool "Console commands: flashwp"
	default y
	help
	  Enables various console commands:

	     flashwp - change write-protection settings

config PLATFORM_EC_CONSOLE_CMD_SYSJUMP
	bool "Console command: sysjump"
	default y
	help
	  Enables the sysjump console command used for testing and verifying
	  that we're able to jump between images. Normally, in an EC build,
	  there will exist 2 images (sometimes more): read-only (RO) and
	  read-write (RW). This console command allows us to manually jump
	  between the various images (or even to a random starting address) by
	  copying the image data from flash to ram, then jumping to the image's
	  entry point.

config PLATFORM_EC_EXTERNAL_STORAGE
	bool "Flash is stored external to the EC"
	default y if SOC_FAMILY_NPCX
	help
	  This indicates that the EC's flash is stored separately and is it
	  not possible execute directly from it. Code must be loaded from
	  the flash into internal SRAM before it can be executed. It is still
	  possible to read and write the flash.

config PLATFORM_EC_MAPPED_STORAGE
	bool "Flash is mapped into the EC's address space"
	default y if SOC_FAMILY_NPCX
	help
	  This indicates that the EC's flash is directly mapped into
	  its address space. This makes it easier to read and write the flash.
	  If this is not defined, the flash driver must implement
	  flash_physical_read().
