# For this to work:
# - io386 module needs to be enabled in board config (sandy/ivy/haswell know to work)
# - coreboot config need to enable CONFIG_BOOTMEDIA_LOCK_CONTROLLER=y without enabling CONFIG_INTEL_CHIPSET_LOCKDOWN
# - io386 module needs to be enabled in board config
# - <Skylake: coreboot config need to enable CONFIG_BOOTMEDIA_LOCK_CONTROLLER=y without enabling CONFIG_INTEL_CHIPSET_LOCKDOWN
# - >=Skylake: same as above and CONFIG_SOC_INTEL_COMMON_SPI_LOCKDOWN_SMM=y, CONFIG_SPI_FLASH_SMM=y and mode (eg: CONFIG_BOOTMEDIA_LOCK_WHOLE_RO=y)
# - Heads is actually doing the CONFIG_INTEL_CHIPSET_LOCKDOWN equivalent here.
# TODO: If more platforms are able to enable CONFIG_INTEL_CHIPSET_LOCKDOWN in the future, have board config export APM_CNT and FIN_CODE and modify this script accordingly
#include ash shell functions (TRACE requires it)
