Yanir Levin 6df14b432e arc: cache: Support region operations, SLC, and entire cache operations
Added configurable support for L1 cache region operations,
which offers improved performance over line operations.
Added configurable support for SLC (system level cache).
Added support for entire cache operations: flush_all,
invd_all, flush_and_invd_all.

The Zephyr Project is a scalable real-time operating system (RTOS) supporting
multiple hardware architectures, optimized for resource constrained devices,
and built with security in mind.

The Zephyr OS is based on a small-footprint kernel designed for use on
resource-constrained systems: from simple embedded environmental sensors and
LED wearables to sophisticated smart watches and IoT wireless gateways.

The Zephyr kernel supports multiple architectures, including ARM (Cortex-A,
Cortex-R, Cortex-M), Intel x86, ARC, Tensilica Xtensa, and RISC-V,
SPARC, MIPS, and a large number of `supported boards`_.
