Sync these files, obtained from Linux v5.15. This adds a devicetree file for rpi_4 which was not there before. Testing shows no change so far as I can see: - boots to U-Boot prompt on rpi0, rpi2 - boots to distro on rpi3 - boots to distro on rpi4 I am assuming that syncing with Linux is safe, but the maintainer should know for sure.
