* zephyr: Enable link time optimization (LTO)Keith Short2021-03-241-1/+1
| | | | | | | | | | | | | | | | | | | The upstream Zephyr repo does not support LTO. Reconfigure the platform/ec source files into a cmake library so the LTO option can be enabled for all the platorm/ec sources. This reduces the Volteer flash image size by 9176 bytes.

* zephyr: migrate arch_panic_set_reason to use __override_protoYuval Peress2021-02-181-5/+0

By using the __override_proto it is possible to provide the default noop implementation while still allowing new cores to implement their own custom implementation.
