From 097f1200bf7ea19fb39ccf538a07a153260a7763 Mon Sep 17 00:00:00 2001 From: Jose Ignacio Tornos Martinez Date: Mon, 11 Mar 2024 17:22:38 +0100 Subject: [PATCH] kbuild: rpm-pkg: add dtb files in kernel rpm Some architectures, like aarch64 ones, need a dtb file to configure the hardware. The default dtb file can be preloaded from u-boot, but the final and/or more complete dtb file needs to be able to be loaded later from rootfs. Add the possible dtb files to the kernel rpm and mimic Fedora shipping process, storing the dtb files in the module directory. These dtb files will be copied to /boot directory by the install scripts, but add fallback just in case, checking if the content in /boot directory is correct. Mark the files installed to /boot as %ghost to make sure they will be removed when the package is uninstalled. Tested with Fedora Rawhide (x86_64 and aarch64) with dnf and rpm tools. In addition, fallback was also tested after modifying the install scripts.
