PR1395/bsps
* Updated the changes from RTEMS-4.8.0, which were made since Oct. 2007.
* 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
* for BSP_SHARED_HANDLER_SUPPORT.
