  • Added generic Micro FrameBuffer? interface for MicroWindows?. This interface allows MicroWindows? to under RTEMS. A sample driver has been developed for the pc386 BSP. See pc386/fb_vga.c as a sample.
  • Added Uniform Input Device interface for MicroWindows?. See PC386 bsp for sample drivers for mouse and keyboard (console).
  • mw-bf: New directory.
  • Makefile.am, configure.in, wrapup/Makefile.am: Account for mw-fb.
  • mw-fb/Makefile.am: New file.
  • mw-fb/mw_fb.c: New file.
  • mw-fb/mw_fb.h: New file.
  • mw-fb/mw_uid.c: New file.
  • mw-fb/mw_uid.h: New file.
  • Property mode set to 100644
