VxWorks 5.4嵌入式操作系统, Tornado II开发平台BSP包的移植

Here is an explanation of how to include TFFS support in this BSP.
Makefile:
  - Add MACH_EXTRA configuration macro as follows.
      MACH_EXTRA = sysTffs.o
  - Add following lines at the end of the Makefile
      # Rules to build TFFS objects
      VPATH=../../src/drv/tffs
      EXTRA_INCLUDE=-I$(TGT_DIR)/h/tffs
config.h:
  - Define INCLUDE_TFFS or INCLUDE_PCMCIA configuration macro as follows.
      #define INCLUDE_TFFS
      or
      #define INCLUDE_PCMCIA
    INCLUDE_TFFS pulls in and uses its own PCIC(PCMCIA controller chip) driver.
    INCLUDE_PCMCIA uses a driver provided by PCMCIA package.  
    The TFFS's PCIC driver doesn't check a type of PC card and it assumes the
    accessing PC card is a flash PC card.  However, the size of the driver is
    small.  Thus it might be suitable for people who have memory constraint.
    On the other hand, the PCMCIA package checks a type of PC card and allows
    TFFS driver to access the PC card only if it is a flash PC card. 
  - Define INCLUDE_SHOW_ROUTINES to link in tffsShow() which shows 
    a relationship between a drive number and a socket interface.
  - Define SYS_WARM_TFFS_DRIVE as follows:
      #define SYS_WARM_TFFS_DRIVE     0       /* 0 = c: (DOC) */
  - Define INCLUDE_TFFS if you define INCLUDE_PCMCIA as follows:
      #ifdef  INCLUDE_PCMCIA
      #define INCLUDE_ATA		/* include ATA driver */
      #define INCLUDE_SRAM		/* include SRAM driver */
      #define INCLUDE_TFFS		/* include TFFS driver */
      #ifdef  INCLUDE_NETWORK
      #define INCLUDE_ELT		/* include 3COM EtherLink III driver */
      #endif  /* INCLUDE_NETWORK */
      #endif  /* INCLUDE_PCMCIA */
sysLib.c
  - If your C: drive is Disk On Chip and you are booting from it instead of 
    floppy disk, set sysWarmType global variable to 3 for warm start from 
    the Disk On Chip.
