Currently Zephyr only ARM CPUs of the Cortex-M3/M4 family (armv7-m), making it incompatible with smaller platforms that are based on Cortex-M0/M0+.
Adding support for Cortex-M0/M0+ would allow Zephyr to be used in a larger range of devices, such as nRF51.
- Change the ARM code so it can be compatible with armv6-m
- Add Kconfig options that are relevant to Cortex-M0/M0+
