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

 	8) PCI_ENDPOINT_TEST_IRQ_TYPE
 	9) PCI_ENDPOINT_TEST_IRQ_NUMBER
 
-*) PCI_ENDPOINT_TEST_MAGIC

 This register will be used to test BAR0. A known pattern will be written
 and read back from MAGIC register to verify BAR0.

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