+Subject: [PATCH 1/1] 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.
