When this option is enabled, the CBFS code will look for a file in the
|
||||
RO (COREBOOT) region, if it isn't available in the active RW region.
|

This option makes sense only if CONFIG_VBOOT was enabled in the coreboot.

This option enables hash verification of CBFS files in RO (COREBOOT) and RW regions.
