From 086283ed7f1886de05407bc75dd4c070c78a6f50 Mon Sep 17 00:00:00 2001 From: Lothar Felten Date: Mon, 8 Oct 2018 13:29:44 +0200 Subject: [PATCH] Fix include guards for older kernel/u-boot sources Linux kernels before 4.17 and U-Boot versions before 2018.07 use libfdt include guards with leading underscores. Those have been removed in dtc-1.4.7. This patch handles both include guard types and allows the compilation of older Linux kernel and u-boot sources.
