- 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.
