if PLATFORM_EC_FLASH_CROS
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_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"
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().
