[yocto] [meta-raspberrypi] How to modify KERNEL_DEVICETREE?

[Andrei Gherzan]

Hi,

You need to make that variable available in both sdcard generation code
which resides in the image recipe and in the kernel recipe. You can do this
by modifying that variable from local.conf (distro would work too I think
but it doesn't sounds like the right place to be).
