    This is actually a problem I had to deal with way in the begging of
    ARM64. What was done in the github tree was to have the one of the DTS
    files(in this case 64) #include the 32 bit dts. That way it's not
    needed to have the symbolic link and install should work.

    I know it's ulgy, but it works...

    Take a look at:
    https://github.com/raspberrypi/linux/blob/rpi-4.10.y/arch/arm64/boot/dt
    s/broadcom/bcm2710-rpi-3-b.dts

    Here is what the file contains:
    #define RPI364

    #include "../../../../arm/boot/dts/bcm2710-rpi-3-b.dts"
