| 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. |

| [ThomasDS: also update fdt.h which has the same issue, seen on U-Boot |
| 2011.03] |
