- 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.
