-	* network/if_1GHz/if_wm.c: fixed some bugs in the 1GHz driver.
-	* pci/pci_interface.c:
-	  + Enabled PCI "Read", "Read Line", and "Read Multiple"
-	  +  Agressive Prefetch to improve the performance of the PCI based
-	     applications (e.g. 1GHz NIC).
-	* irq/BSP_irq.c : Replaced the irq/irq.c, and used GT_GPP_Value
-	register to monitor the cause of the level sensitive interrupts.
-	This unique solution solves various bugs in the 1GHz network drivers
-	Fixed bugs in compute_pic_masks_from_prio()
-	* pci/pci.c : Updated it to be consistent with the original pci.c
-	* written by Eric Valette.  There is no change in its function.
-	* irq/irq_init.c : set defaultIrq->next_handler to be 0
