It has routines for initializing device resources and providesBSP-specific routines for Intel (formerly DEC) 21040, 21140, and 21143Ethernet PCI bus controllers found on the system.The number of supported devices that can be configured for a particular systemis finite and is specified by the DEC21X40_MAX_DEV configuration constant.This value, and the internal data structures using it, can be modified in thisfile for specific implementations.NOTEThis module has only been tested with the following Ethernet cards:.IP "21040 controller"Digital DE435..IP "21140 controller"D-Link DFE-500TX and Kingston KNE-100TX..IP "21143 controller"Intel (formerly DEC) EB143 evaluation card, Kingston KNE-100TX, andLongshine 8038 TXD..LPSEE ALSO:.I "Digital Semiconductor 21143 PCI/CardBus Fast Ethernet LAN Controller,".I "Digital Semiconductor 21143 10/100Base-TX Evaluation Board User's Guide."*/#if defined(INCLUDE_DEC21X40_END)/* includes */#include "end.h"#include "drv/end/dec21x40End.h"/* defines *//* specify the maximum number of physical devices to configure */#define DEC21X40_MAX_DEV       (8)/* BSP specific DEC 21x4x ethernet device type constants */#define DEC_TYPE_EB143         (1)   /* DEC 21143 10/100Base-TX */#define DEC_TYPE_DC140         (2)   /* DEC 21140 10/100Base-TX */#define DEC_TYPE_DC040         (3)   /* DEC 21040 10/100Base-TX *//* untested board types */#define DEC_TYPE_LC82C168      (4)   /* Lite-On PNIC */#define DEC_TYPE_MX98713       (5)   /* Macronix 98713 PMAC */#define DEC_TYPE_MX98715       (6)   /* Macronix 98715 PMAC */#define DEC_TYPE_AX88140       (7)   /* ASIX AX88140 */#define DEC_TYPE_PNIC2         (8)   /* Lite-On PNIC-II */#define DEC_TYPE_COMET         (9)   /* Comet family */#define DEC_TYPE_COMPEX9881   (10)   /* Compex 9881 */#define DEC_TYPE_I21145       (11)   /* Intel 21145 *//* DEC 21040/21140/21143 driver user flags */#define DEC_USR_FLAGS_143     (DEC_USR_21143)#define DEC_USR_FLAGS_140     (DEC_USR_BAR_RX | DEC_USR_RML    | \                               DEC_USR_CAL_08 | DEC_USR_PBL_04 | \                               DEC_USR_21140  | DEC_USR_SF)#define DEC_USR_FLAGS_040     (DEC_USR_BAR_RX | DEC_USR_CAL_08 | DEC_USR_PBL_04)/* untested board flags */#define PNIC_USR_FLAGS        (DEC_USR_21143)#define MX98713_USR_FLAGS     (0)#define MX98715_USR_FLAGS     (0)#define AX88140_USR_FLAGS     (0)#define PNIC2_USR_FLAGS       (0)#define COMET_USR_FLAGS       (0)#define COMPEX9881_USR_FLAGS  (0)#define I21145_USR_FLAGS      (0)/* DEC 21x4x PCI Vendor and Device IDs */#define DEC21X4X_PCI_VENDOR_ID     (0x1011)  /* DEC PCI vendor ID */#define DEC_PCI_VENDOR_ID          (0x1011)  /* DEC PCI vendor ID      */#define DEC21143_PCI_DEVICE_ID     (0x0019)  /* 21143 PCI device ID */#define DEC21140_PCI_DEVICE_ID     (0x0009)  /* 21140 PCI device ID */#define DEC21040_PCI_DEVICE_ID     (0x0002)  /* 21040 PCI device ID *//* untested board PCI Vendor and Device IDs */#define PNIC_PCI_VENDOR_ID         (0x11AD)  /* Lite-On Communications */#define PNIC_PCI_DEVICE_ID         (0x0002)#define PNIC2_PCI_DEVICE_ID        (0xc115)#define MACRONIX_PCI_VENDOR_ID     (0x10d9)  /* Macronix */#define MX98713_PCI_DEVICE_ID      (0x0512)#define MX98715_PCI_DEVICE_ID      (0x0531)#define ASIX_PCI_VENDOR_ID         (0x125B)  /* Asix Electronics Corp. */#define AX88140_PCI_DEVICE_ID      (0x1400)#define COMET_PCI_VENDOR_ID        (0x1317)  /* Admtek Inc. */#define COMET1_PCI_DEVICE_ID       (0x0981)#define COMET2_PCI_DEVICE_ID       (0x0985)#define COMET3_PCI_DEVICE_ID       (0x1985)#define COMPEX_PCI_VENDOR_ID       (0x11F6)  /* Powermatic Data Systems */#define COMPEX9881_PCI_DEVICE_ID   (0x9881)#ifndef INTEL_PCI_VENDOR_ID#define INTEL_PCI_VENDOR_ID        (0x8086)  /* Intel Corporation */#endif /* INTEL_PCI_VENDOR_ID */#define I21145_PCI_DEVICE_ID       (0x0039)#define DAVICOM_PCI_VENDOR_ID      (0x1282)  /* Davicom Semiconductor */#define DAVICOM9100_PCI_DEVICE_ID  (0x9100)#define DAVICOM9102_PCI_DEVICE_ID  (0x9102)#define ACCTON_PCI_VENDOR_ID       (0x1113)  /* Accton Technology Corp. */#define EN1217_PCI_DEVICE_ID       (0x1217)/* forward declarations */LOCAL UINT32 sysDecDevToType (UINT32, UINT32, UINT8);/* locals */LOCAL UINT32 decUnitsFound = 0;   /* the number of physical units found *//* * This array defines the board-specific PCI resources.
