It's used in the Vivaldi tablet (based on zenithink c71) which uses Plasma Active as it's UI.
Software
Amlogic appears to be primarily focusing on Android support for this board. Much of the software stack is documented on their "openlinux wiki":http://openlinux.amlogic.com/wiki/index.php/Arm. You can download the rootfs from "here":http://openlinux.amlogic.com/download/linux/ARM/filesystem/ and the kernel from "here":http://openlinux.amlogic.com/download/linux/ARM/kernel/.

Compiling Qt5
$ mkdir build && cd build
$ export QTSRCDIR=<path_to_qt5> # top level qt5.git and not qtbase
$ export TOOLCHAIN_PATH=<path_to_toolchain> # see section above
$ export SYSROOT=<path_to_rootfs>
$ export PREFIX=<install_path_on_target>
$ $QTSRCDIR/configure -device linux-arm-amlogic-8726M-g++ -force-pkg-config -device-option CROSS_COMPILE=$TOOLCHAIN_PATH/arm-2010q1/bin/arm-none-linux-gnueabi- -sysroot $SYSROOT -prefix $PREFIX -make libs -opensource -confirm-license
$ make module-qtbase module-qtdeclarative
$ make install # will install Qt into the $SYSROOT/$PREFIX
