From 3a4e5944c96c0d4a421132096f88d972569cb307 Mon Sep 17 00:00:00 2001 From: Sumit Garg <sumit.garg@linaro.org> Date: Thu, 22 Feb 2024 15:06:00 +0530 Subject: [PATCH] Makefile: Allow upstream DT subtree to provide DT includes Allow platforms to reuse DT headers and dtsi includes directly form upstream DT subtree which will be frequently synced with Linux kernel. This will further allow us to drop corresponding DT includes copy from U-Boot tree. Also, since the DT includes from upstream DT subtree are done after DT includes from U-Boot tree, so it shouldn't cause any conflicts.
