+Subject: [PATCH] tools: Include U-Boot libfdt headers from their actual path
+
+There are no headers for libfdt in lib/libfdt, as they are instead
+located in scripts/dtc/libfdt. Specifying lib/libfdt for headers
+inclusion in host tools results in using the system libfdt headers,
+which is not what we want. Change this to the proper path.
