Traditionally PCI RC has always been validated by using standard
PCI cards like ethernet PCI cards or USB PCI cards or SATA PCI cards.
@@ -23,65 +28,76 @@ The PCI endpoint test device has the following registers:
8) PCI_ENDPOINT_TEST_IRQ_TYPE
9) PCI_ENDPOINT_TEST_IRQ_NUMBER
-*) PCI_ENDPOINT_TEST_MAGIC
+* 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.
-*) PCI_ENDPOINT_TEST_COMMAND:
+* PCI_ENDPOINT_TEST_COMMAND
This register will be used by the host driver to indicate the function
that the endpoint device must perform.

This register contains the source address (RC buffer address) for the
COPY/READ command.
