RSS Bot Posted December 13, 2023 Posted December 13, 2023 Description This PR adds a board config file for RPi 5. While on it, the PR also removes dependency on flash-kernel. Instead some custom scripts are added into the bsp package for installation of updated dtb, kernel and initrd files. Using both rpi4b and rpi5b will produce images compatible with rpi5, but the image created with BOARD=rpi5b will not run on older hardware. The kernel config, patches etc are shared between both boards. To prevent creating new family for RPI5 specific kernel, I have added support for something I call kernel variants. This is basically going to be almost same kernel with extremely small changes that doesn't justify creating new family and yet still needs a different kernel deb file. This is being achieved by adding a suffix to the kernel similar to how we add suffix to bsp files when using flash-kernel among other things. Lastly I have also changed config.txt and cmdline.txt to match official raspberry pi versions as much as possible How Has This Been Tested? Please describe the tests that you ran to verify your changes. Please also note any relevant details for your test configuration.
