/*
 * The ARM targets equipped by cache should include
 * which kind and implementation they support.
 * Next options are available
 *
 * c/src/lib/libbsp/arm/shared/armv467ar-basic-cache/cache_.h
 *   basic ARM cache integrated on the CPU core directly
 *   which requires only CP15 oparations
 *
 * c/src/lib/libbsp/arm/shared/arm-l2c-310/cache_.h
 *   support for case where ARM L2C-310 cache controller
 *   is used. It is accessible as mmaped peripheral.
 *
 * c/src/lib/libbsp/arm/shared/armv7m/include/cache_.h
 *   Cortex-M specific cache support
 *
 * Cache support should be included in BSP Makefile.am
 *
 * Example how to include cache support
 *
 * # Cache
 * libbsp_a_SOURCES += ../../../libcpu/shared/src/cache_manager.c
 * libbsp_a_SOURCES += ../shared/include/arm-cache-l1.h
 * libbsp_a_SOURCES += ../shared/armv467ar-basic-cache/cache_.h
 * libbsp_a_CPPFLAGS += -I$(srcdir)/../shared/armv467ar-basic-cache
