** B69 Bios history **

Name convention is 
 seco_apollolake_B69_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 (yyyymmdd)
  RESTRICTION        Reflects the PCIE lanes aggregation on the edge connector
  
  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
