From 04ab57d20009d85eb566e83ae6fe1dcea4db7300 Mon Sep 17 00:00:00 2001 From: Randolph Sapp Date: Tue, 2 May 2023 11:56:12 -0500 Subject: [PATCH] kernel-devicetree: allow specification of dtb directory Fedora/Redhat and Arch are somewhat standardized on their dtb directory structure. Let's add some flags to configure yocto to mimic that behavior. Add the following variables to the kernel class: - KERNEL_DTBDEST (controls the destination directory for dtbs) - KERNEL_DTBVENDORED (controls if vendor subdirectories are to be respected) Currently KERNEL_DTBDEST is expected to be a subdir of KERNEL_IMAGEDEST and KERNEL_DTBVENDORED is expected to be "true"/"false". This only applies to the package directory structure. The deploydir structure is purposely left untouched for compatibility with existing recipes. By default this is configured to behave the same as the current recipe and produce a flat dtb directory at KERNEL_IMAGEDEST.
