-choice PLATFORM_EC_BOARD_VERSION_SOURCE
- prompt "Select the source of the board version number"
- optional
- help
- This allow selection of the source of the board version number
- information. Several options are available, but BOARD_VERSION_CBI is
- preferred for new boards, so long as the hardware supports it (i.e.
- has an EEPROM).
-
-config PLATFORM_EC_BOARD_VERSION_CBI
- bool "Chromium OS Board Info (CBI)"
- depends on PLATFORM_EC_CBI_EEPROM
- help
- Choose this if the board version comes from Chromium Board Info
- within the EEPROM. This is the recommended approach and is used on
- newer boards. The version information is written into the EEPROM as
- part of the factory process.
-
-config PLATFORM_EC_BOARD_VERSION_GPIO
- bool "Strapping GPIOs"
- help
- Choose this if the board version is encoded with three GPIO signals
- (GPIO_BOARD_VERSION1, GPIO_BOARD_VERSION2 and GPIO_BOARD_VERSION3)
- forming the 3-digit binary number. GPIO_BOARD_VERSION1 is the LSB.
- This provides 8 possible combinations.
-
- The GPIOs should have external pull-up/pull-down resistors installed
- at the factory to select the correct value.
