/* usrConfig.c - user-defined system configuration library *//*DESCRIPTIONThis library is the WRS-supplied configuration module for VxWorks.  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"*/#include "vxWorks.h"			/* always first */#include "config.h"			/* board support configuration header */#include "usrConfig.h"			/* general configuration header */#ifdef INCLUDE_USB    #include "usbPciStub.c" #endif#ifdef INCLUDE_OHCI_INIT    #include "usrUsbHcdOhciInit.c"#endif#ifdef INCLUDE_USB_INIT    #include "../comps/src/usrUsbInit.c"#endif#ifdef INCLUDE_USB_MS_CBI_INIT    #include "../comps/src/usrUsbCbiUfiDevInit.c"#endif#ifdef INCLUDE_OHCI_PCI_INIT    #include "../comps/src/usrUsbPciOhciInit.c"#endif#ifdef INCLUDE_USBTOOL    #include "../comps/src/usrUsbTool.c"#endif#ifdef INCLUDE_SELF_SHELL#include "shell.c"#endif#include "usrKernel.c"			/* kernel configuration */#include "usrExtra.c"			/* conditionally included packages */extern 	void usrShell(void);#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.
