| Enforce correct -march option |
| |
| Buildroot uses a normal ARM compiler to build the AM33X CM3 firmware |
| (which runs on a Cortex-M3 processor), but Buildroot will have a |
| default -march value that doesn't necessarily match the one needed for |
| Cortex-M3, leading to build failures (gcc complains that the |
| -mcpu=cortex-m3 option being passed is not compatible with the |
| selected -march). |
| |
| Fix this by explicitly indicating -march=armv7-m. |
