    Only BSP CPU writes CMOS in bootblock code
    CMOS accesses are not safe for multi-processor and only the BSP CPU
    should count reboots and test CMOS sanity.
    A questionable single byte CMOS read access from AP CPUs remains.
    AP CPUs should always select the same romstage prefix as BSP CPU.
