Allow coreboot to initialize CMOS if checksum is invalid.
If a file "cmos.default", type "cmos default"(0xaa) is in CBFS, a wrong checksum leads to coreboot rewriting the first 128 bytes (except for clock data) with the data in cmos.default, then reboots the system so every component of coreboot works with the same set of values.
