commit 35fe369b90b5faa5e5f6f259d29dd7fb63bdbbd2

    Extend smbios api to allow runtime change of mainboard serial and version
    
    This patch extends the current smbios api to allow changing mainboard
    serial and version during coreboot runtime. This is helpful if you
    have an EEPROM etc. to access these informations and want to add
    some quirks for broken hardware revision for the linux kernel.
    This could be done via DMI_MATCH marco.
