config PLATFORM_EC_BYPASS_CBI_EEPROM_WP_CHECK
bool "Bypass CBI EEPROM Write Protect"
help
Bypass the CBI EEPROM write protect checks. This should ONLY be
defined during bringup, and should never be defined on a shipping or
release platform.
When defined, ectool can be used to reprogram all CBI fields,
regardless of the state of the hardware write protect.
config PLATFORM_EC_EEPROM_CBI_WP
bool "EC can independently set the CBI EEPROM WP signal"
help
Define this if the EC can independently set the CBI EEPROM WP
signal. The accompanying hardware must ensure that the CBI WP gets
latched and is only reset when EC_RST_ODL is asserted.
choice PLATFORM_EC_CBI_STORAGE_TYPE
prompt "Select CBI storage Type"
optional
help
CBI is a means for accessing board information, typically set
during the factory process. This allows selection of the physical
storage of CBI source.
See here for detailed information on CBI:
https://chromium.googlesource.com/chromiumos/docs/+/HEAD/design_docs/cros_board_info.md
config PLATFORM_EC_CBI_EEPROM
bool "CBI EEPROM support"
depends on EEPROM
help
Enables full Chromium OS Board Info (CBI) support, with CBI data
stored in an on-board EEPROM.
config PLATFORM_EC_CBI_GPIO
bool "CBI GPIO support"
help
Enables Chromium OS Board Info (CBI) from strapping pins. EC reads
the BOARD ID and SKU ID from GPIOs and then substantiate in-memory
CBI for AP to query.
