| 4 | Subject: [PATCH] Makefile: Add the libfdt to the Makefile system |
| 5 | |
| 6 | Add the libfdt into Makefile system. The libfdt uses const value and |
| 7 | thus gcc will enable the stack guard. The stack guard will fail the |
| 8 | compile. Add -fno-stack-protector to fix it. |

| 10 | Issue-Id: SCM-3814 |
| 11 | Upstream-Status: Inappropriate [other] |
| 12 | Implementation pending further discussion |
| 13 | Signed-off-by: Jaxson Han <jaxson.han@arm.com> |
