SMP support for ARM architecture

Krzysztof Walczak


For our multicore ARM based project we would like to use SMP and affinity mechanism in Zephyr. When digging into the code I found that it is not implemented.
Mainly, there is an implementation of arch_switch() missing needed by SMP. Can someone give me any guideline as to what would be required for implementation to have an SMP/afinity mechanism operational in Zephyr on ARM platform.
