Execute the $board-config.sh again.

Subject: [PATCH] Sunxi adaptation for mali r3p2-01rel2 kernel module
Tested only on A10 and A20.
TODO:
- bus addresses vs. physical addresses?
- umplock?
- power management (disable clocks when idle)?
- drm upgrade (and also fix compatibility with xf86-video-modesetting)?

After apply the patch, then compile the kernel again.
The default frambuff in pcDuino series is 640×480. Then you can modify the 43th Row static char *screen0_output_mode=”1920x1080p50″ under drivers/video/sunxi/disp/dev_fb.c

$make -j 8 firmware_install modules_install INSTALL_MOD_PATH=../modules ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf-
After the compile finish, you will get the new uImage under the arch/arm/boot/uImage. And get the new kernel modules under ../modules/lib/modules/.
Copy the uImage to the another part of TF card. Copy the new 3.4.79 kernel module to the system under the /lib/modules/，reboot the system, then you will find the screen character display 1080P.

3,Download the qt-everywhere-opensource-src-5.3.2

#cp ../Qt5.3.2forPcDuino3/linux-pcDuino3-g++ qtbase/mkspecs/devices/ -rf
Here need to notice open the linux-pcDuino3-g++
You need to modify to your own path .
5，Modify the Qt source code qtbase/src/plugins/platforms/eglfs/qeglfshooks_stub.cpp

Qt is now configured for building. Just run 'make'.
Once everything is built, you must run 'make install'.
Qt will be installed into /usr/local/qt5
Prior to reconfiguration, make sure you remove any leftovers from
the previous build.
#make -j 8
#sudo make install
I use quad computer, compile around 2 hours
After the compile, the responsible library will be installed to TF card /usr/local/qt5,the according develop tool will accord to the local /usr/local/qt5
