The RP1 driver uses the infrastructure enabled by OF_OVERLAY config option. Enable that option in defconfig in order to produce a kernel usable on RaspberryPi5 avoiding to enable it separately. Signed-off-by: Andrea della Porta <andrea.porta@xxxxxxxx> --- This patch is *OPTIONAL* since I'm not sure if OF_OVERLAY is a desirable feature to have enabled by default. It would be advisable to have it included so that 'make defconfig' can produce a kernel config that will work out of the box on Rpi5, otherwise OF_OVERLAY has to be enabled separately.
I think this isn't a good approach to convince the arm64 maintainer. This change is not really optional for the Raspberry Pi 5 and possible users/testers/CI rely on a working default configuration. So my first suggestion would be to provide a scripts/bloat-o-meter output (before/after). Based on this the maintainer can better decided. In case this change is still rejected, we still have the option of something like this [1] Best regards [1] - https://patchwork.kernel.org/project/linux-kbuild/patch/20200203184820.4433-3-nsaenzjulienne@xxxxxxx/
