RTEMS graphic testing on RPi

[Pavel Pisa]

Hello Qiao and Joel,

I have rerun testing of actual RSB mainline testing
on RPi B device. Generally works well.

Used instructions included for archival there

  git clone git://git.rtems.org/rtems-source-builder.git
  cd rtems
  ../source-builder/sb-set-builder \
    --prefix=/opt/rtems4.11 \
    --rtems-bsp=arm/raspberrypi \
    --log=graphic-build-log.txt \
    --with-rtems-bsp=raspberrypi \
    --pkg-tar-files \
    4.11/graphics/freetype2.bset \
    4.11/graphics/libjpeg.bset \
    4.11/graphics/libpng.bset \
    4.11/graphics/libtiff.bset \
    4.11/graphics/t1lib.bset \
    4.11/graphics/microwindows.bset


There are minor problems with t1lib patch and libpng version changes

 # Prepare the source code.

We should get rid of microwindows patches or at least limit them
to the configuration file only
  microwindows-0.93-dev.diff
  microwindows-0.93-dev-without-keyboard.diff

I have some changes already included in my repo branch for RTEMS.
I.e. keyboard patch

  https://github.com/ppisa/microwindows/commit/57b3eb772dc4175bf356736fe239331c8e125721

I have there configuration file based override of graphic driver
even for RTEMS

  https://github.com/ppisa/microwindows/commit/a85ee935e4ff0f569455004d9a71cc3d218a7ca6

and even null KBD handling should land there.

I hope to find some spare time for that in reasonable time.

As of the 4.11/graphics/nxlib.bset, it does not build for RPi because
keyboard mapping is missing for that platform.

   #include <rtems/keyboard.h>
                              ^
I do not see that as big problem because NXlib is mainly for remote
graphic (i.e. X like protocol) and if I see well the NXlib is absorbed
now in Microwindows directly

See Gregory Haerr actual repo

  https://github.com/ghaerr/microwindows/tree/master/src

Generally, it is great that the RTEMS graphic support build
is included in official RSB repo now and runs on target.

Best wishes,

             Pavel
