  • 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.
  • network/if_1GHz/if_wm.c : fixed some bugs in the 1GHz driver.
  • irq/BSP_irq.c : added supports for shared IRQ.
  • 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()
  • Property mode set to 100644
