Itcontains the root task, the primary system initialization routine, thenetwork initialization routine, and the clock interrupt routine.The include file config.h includes a number of system-dependent parameters usedin this file.In an effort to simplify the presentation of the configuration of vxWorks,this file has been split into smaller files.  These additional configurationsource files are located in ../../src/config/usr[xxx].c and are #included intothis file below.  This file contains the bulk of the code a customer islikely to customize.The module usrDepend.c contains checks that guard against unsupportedconfigurations such as INCLUDE_NFS without INCLUDE_RPC.  The moduleusrKernel.c contains the core initialization of the kernel which is rarelycustomized, but provided for information.  The module usrNetwork.c nowcontains all network initialization code.  Finally, the module usrExtra.ccontains the conditional inclusion of the optional packages selected inconfigAll.h.The source code necessary for the configuration selected is entirelyincluded in this file during compilation as part of a standard build inthe board support package.  No other make is necessary.INCLUDE FILES:config.hSEE ALSO:.tG "Getting Started, Cross-Development"* 01a 2006/09/06 李普軍 添加控制網(wǎng)口的初始化* 01b 2006/09/09 chenhuili 在進行控制面網(wǎng)口初始化后，        添加 usrNetInit (BOOT_LINE_ADRS) initialize network support，解決        WDB不能正常工作的問題 */#include "vxWorks.h"			/* always first */#include "config.h"			/* board support configuration header */#include "usrConfig.h"			/* general configuration header */#include "usrDepend.c"			/* include dependency rules */#include "usrKernel.c"			/* kernel configuration */#include "usrExtra.c"			/* conditionally included packages *//* lipujun 2006-6-30 11:02 add */#ifdef DRV_DDR_MEM_SIZE_512Mextern void drv_bsp_mem_add ( void );#endif /* DRV_DDR_MEM_SIZE_512M */    #ifdef INCLUDE_USER_APPL   /* 加應(yīng)用代碼的vxworks *//* 網(wǎng)口初始化接口，單板驅(qū)動軟件提供，李普軍 2006-9-7 14:39 add */extern STATUS  drv_ether_port_comm_init ( UINT8 ucPortType, UINT8 *pucMacAddr, UINT32 *pulIpAddr );extern void inet_ntoa_b        (        struct in_addr inetAddress, /* inet address */        char *         pString      /* where to return ASCII string */        );extern  STATUS bootStructToString        (        char *        paramString, /* where to return the encoded boot line */        BOOT_PARAMS * pBootParams  /* boot line structure to be encoded */        );#endif /* INCLUDE_USER_APPL */#if CPU==SIMNTextern int simUpMutex;extern int win_ReleaseMutex(int hMutex);#endif#ifdef INCLUDE_HTTP#include "http/httpLib.h"		/* Wind Web Server interfaces */#endif#ifdef INCLUDE_COMextern int comLibInit ();#endif#ifdef INCLUDE_DCOMextern int dcomLibInit ();#endif/* defines - must be after include of usrDepend.c */#ifdef	INCLUDE_WDB#define FREE_MEM_START_ADRS (FREE_RAM_ADRS + WDB_POOL_SIZE)#else#define FREE_MEM_START_ADRS FREE_RAM_ADRS#endif#ifdef	INCLUDE_INITIAL_MEM_ALLOCATION#define MEM_POOL_START_ADRS \	    (ROUND_UP(FREE_MEM_START_ADRS, (INITIAL_MEM_ALIGNMENT)) + \	    (INITIAL_MEM_SIZE))#else	/* INCLUDE_INITIAL_MEM_ALLOCATION */#define MEM_POOL_START_ADRS FREE_MEM_START_ADRS#endif	/* INCLUDE_INITIAL_MEM_ALLOCATION *//* global variables */int		consoleFd;		/* fd of initial console device */char		consoleName[20];	/* console device name, eg.
