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.

Use CASA atomic instructions. Defined by SPARC V9 and available
in some LEON processors.
# The SPARC V8 ABI allocates a stack frame of minimum 96 byte for each SAVE

COVERAGE: Fix COVERAGE_GCOV dependencies CONFIG_COVERAGE has been incorrectly used to change other kconfig options (stack sizes, etc) code defaults, as well as some samples behaviour, which should not have dependend on it. Instead those should have depended on COVERAGE_GCOV, which, being the one which adds special code and temporary RAM storage for embedded targets, require changes to many features. When building for the native targets, all this was unnecessary. => Fix the dependency. Signed-off-by: Alberto Escolar Piedras <alberto.escolar.piedras@nordicsemi.no>
