 Traditionally PCI RC has always been validated by using standard
 PCI cards like ethernet PCI cards or USB PCI cards or SATA PCI cards.

-*) PCI_ENDPOINT_TEST_MAGIC

 This register will be used to test BAR0. A known pattern will be written

 This register will be used by the host driver to indicate the function
 that the endpoint device must perform.
