wrSbc8255的vxWorks BSP驱动源码

                 README: Wind River SBC8255 (wrSbc8255)

This file contains board-specific information for the Wind River SBC8255
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., wrSbc8255/target.nr)
provides board-specific information necessary to run VxWorks, and
should be read before this BSP is used.
