Kernel 4.14 for BananaPi R2

Requirements

On a x86/x64-host you need cross compile tools for the armhf architecture (bison and flex-package are needed for kernels >=4.16):

sudo apt install gcc-arm-linux-gnueabihf libc6-armhf-cross u-boot-tools bc make gcc libc6-dev libncurses5-dev libssl-dev bison flex

If you build it directly on the BananaPi-R2 (not recommended) you do not need the crosscompile-packages gcc-arm-linux-gnueabihf and libc6-armhf-cross

(Testing in seperate branch wlan/hdmi/hwnat/hwqos)

• HW-NAT only works between LAN and WAN (bridge unclear, WLan not supported)
• HW-QoS is merged into 4.14-main, but we do not know how to test it
• ACPI-feature means System is powered off, not only halted (power-consumption ~0.2W, no reboot on reset), reboot-problem with soldered power-switch (see frank-w#35). Power-off is also initiated by pressing the power-switch
• VIDEO is hdmi-output (X-server/framebuffer-console)...here some resolutions are not supported by vendor-driver
