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.
