From 2c7686137b8e7b2e5e38cf9bbad30d885a93141e Mon Sep 17 00:00:00 2001 From: Lukas Auer Date: Wed, 21 Aug 2019 21:14:41 +0200 Subject: [PATCH] Makefile: support building SPL FIT images without device trees When building a U-Boot FIT image, the device trees specified by the board are unconditionally built for inclusion in the FIT image. However, not all device tree providers, such as CONFIG_OF_PRIOR_STAGE, require a device tree to be built and bundled with the U-Boot binary. They rely on other mechanisms to provide the device tree to U-Boot. Compilation on boards with these device tree providers fails, because they do not specify a device tree. Change the makefile rules to conditionally build the device trees if CONFIG_OF_SEPARATE, CONFIG_OF_EMBED, or CONFIG_OF_HOSTFILE is selected as device tree provider.
