Routine Description:

  The function will excute with as the platform policy, current policy
  is driven by boot mode. IBV/OEM can customize this code for their specific
  policy action.

Arguments:

  DriverOptionList - The header of the driver option link list

  BootOptionList   - The header of the boot option link list

  ProcessCapsules  - A pointer to ProcessCapsules()

  BaseMemoryTest   - A pointer to BaseMemoryTest()

Returns:

  None.
