6 This is a high-level guide to cache interface and Kconfig options related to
7 cache controllers. See :ref:`cache_api` for API reference material.
9 Zephyr has different Kconfig options to control how the cache controller is
15 instruction cache. The cache controller can be in the core or can be an
16 external cache controller for which a driver is provided.
22 options must be selected when support for data or instruction cache is
25 All the code paths related to cache control must be conditionally enabled
26 depending on these symbols. When the symbol is set the cache is considered
