Gregory Nutt 01b740c66b arch/arm/src/efm32: Support for common vector handling is forced for all EFM32 chips. Yes the architecture provides support for the old-style dedicated vector handling which can never be compiled. Furthermore, the old-style dedicated vector handling is deprecated in favor of common vector handling.
