Yong Cong Sin	de347a4e07	init: support per-core init hook Allow SoC to implement their custom per-core initialization function by selecting `CONFIG_SOC_PER_CORE_INIT_HOOK` and implement `soc_per_core_init_hook()`.

Yong Cong Sin	e54b27b967	arch: define `struct arch_esf` and deprecate `z_arch_esf_t` Make `struct arch_esf` compulsory for all architectures by declaring it in the `arch_interface.h` header. After this commit, the named struct `z_arch_esf_t` is only used internally to generate offsets, and is slated to be removed from the `arch_interface.h` header in the future.

Martin Åberg	88f478108d	sparc: write through switched_from in arch_switch() Write through switched_from in arch_switch() as required by the switch protocol. Also restructure the implementation to better match the template in kernel_arch_interface.h, by removing a wrapper routine and instead use CONTAINER_OF().

Martin Åberg	07160fa153	arch: Add SPARC processor architecture SPARC is an open and royalty free processor architecture. This commit provides SPARC architecture support to Zephyr. It is compatible with the SPARC V8 specification and the SPARC ABI and is independent of processor implementation. Functionality specific to SPRAC processor implementations should go in soc/sparc. One example is the LEON3 SOC which is part of this patch set. The architecture port is fully SPARC ABI compatible, including trap handlers and interrupt context. Number of implemented register windows can be configured. Some SPARC V8 processors borrow the CASA (compare-and-swap) atomic instructions from SPARC V9. An option has been defined in the architecture port to forward the corresponding code-generation option to the compiler. Stack size related config options have been defined in sparc/Kconfig to match the SPARC ABI.
