            I am trying to compile kernel from these sources: https://github.com/Dee-UK/RK3188_tablet_kernel_sources
            With "make nconfig" i made only these changes just to try to see if i can compile bootable kernel:

            System Type:
            ARM system type: Rockchip RK3188
            Enable for Android 4.4 KitKat
            Rockchip SoC Type: RK3188
            RK3188 Board Type: Pipo M8Pro
            Kernel Features:
            Use the ARM EABI to compile the kernel

            But compilation fails because there is no "arch/arm/mach-rk3188/board-pipo-m8pro.c" in sources.
            I only need very basic kernel that has working LCD, touchscreen, USB and audio. Can anyone give me some tips about how to proceed?

            Thanks
