** C24 Bios history **

Name convention is 
 seco_ApolloLake_C24_bios_<AMI_BIOS_TAG>_<BIOS_VERSION>_<RELEASE_DATE>_<RESTRICTION>.bin

Where:
  AMI_BIOS_TAG  Is AMI BIOS Tag used for the project
  BIOS_VERSION  Is SECO BIOS version with this format Major.Minor.Patch
  RELEASE_DATE  Is BIOS Release Date
  RESTRICTION   Is related to bios configuration, pcie aggregation, etc

  4x1 = Four 1-lane PCIe interfaces (default BIOS)
  2x2 = Two 2-lane PCIe interfaces
  2x1 = Two 1-lane PCIe interfaces
  1x2 = One 2-lane PCIe interface
  1x4 = One 4-lane PCIe Interface
    	
  Note: to move from one aggregation to another one, the proper BIOS must be flashed
