Note though that C7's gcc will not build the HardKernel sources successfully, as the Linaro 4.9.x gcc is the 'standard' gcc for them. So I keep a stock Ubuntu image around and boot it occasionally on my dev C2 to get the newest kernel items, and I have built up a process (not yet automated) for upgrading an SD card in my C7 laptop using the Ubuntu image along with the C7 rootfs as on the booting SD. It's dead-simple, really, and involves replacing the kernel files on the FAT boot partition and then the includes and modules from the Ubuntu rootfs. I'd like to do a native build, but I just haven't had the time to build an aarch64 rpm of the linaro 4.9.x toolchain. (It's available for x86_64 as a cross-compiler).
