1. For Intel 82559 controller (fei) work with ks8695p SOHO BSP (embeded ARM922T),
   Need to modify following :
   (1). since ARM922T PCI host bridge doesn't support I/O base mapping, 
        all the I/O base mapping access to fei has to change to memory base mapping.
   (2). 'endDevTbl' is used for ks8695p END driver. For additional PCI bus interface, like 
        fei END driver, create a new 'endDevTbl' ('feiEndDevTbl') for it.
   (3). CPU's 'external interrupt 0' is used for all the PCI interrupt devices.
        Added disable\enable system (CPU) interrupt source for 'external interrupt 0'.

DESCRIPTION
This file contains the board-specific routines for Ethernet adapter
initialisation of Intel (formerly DEC) 21040, 21140 and 21143-based
adapters and Intel Pro 100+ based adapters.

NOTE
At the time of writing, this module has only been tested with the following
Ethernet cards:
    21040 controller: Digital DE435.
    21140 controller: D-Link DFE-500TX
                      Kingston KNE-100TX
    21143 controller: Intel (formerly DEC) EB143 evaluation card.
                      Kingston KNE-100TX
                      Longshine 8038 TXD
    82559 controller: Intel PRO/100+ Management Adapter
                      Intel InBusiness 10/100 PCI Network Adapter

Refer to the BSP reference entry for any eventual limitations or
problems related to the BSP.
