wind river提供的MPC8260的BSP典型代码

                 README: Wind River SBC8260 (wrSbc8260)

This file contains board-specific information for the Wind River SBC8260
target board. Specifically, this file contains information on any BSP
interface changes from previous software or hardware versions, and
contains caveats that the user must be aware of before using this BSP.
Additionally, the target board's manual page entry (i.e., wrSbc8260/target.nr)
provides board-specific information necessary to run VxWorks, and
should be read before this BSP is used.

        Change the "Programming bootrom_uncmp to SBC8260 FLASH" section in the target.nr
        to be more readble.

        Update 'config.h' to support the Wind River H.S.I the new TM driver

        Fixing problem in the function sysAuxClkEnable() in sbcm8260Timer.c
