config PLATFORM_EC_RO_HEADER
bool "RO section includes a header"
default y
depends on CROS_EC_RO
depends on SOC_FAMILY_NPCX
help
The RO image residing on flash memory has a header section. The header
is used on some chips (such as the npcx) to load the image correctly
from flash. The values for offset and size are used by the linker
scripts to generate the header. See core/cortex-m/ec.lds.S for
reference.
config PLATFORM_EC_RO_HEADER_OFFSET
hex "Offset in memory for the location of the header"
default 0x0
help
The offset (in bytes) of the header relative to the start address of
the RO image.
config PLATFORM_EC_RO_HEADER_SIZE
hex "Size of the RO header"
default 0x40 if SOC_FAMILY_NPCX
default 0x0
help
The size of the RO header in bytes. This values should come from the
datasheet of the chip being used.
