The previous cache manager support used a single souce file (cache_manager.c) which included an implementation header (cache_.h). This required the use of specialized include paths to find the right header file. Change this to include a generic implementation header (cacheimpl.h) in specialized source files. Use the following directories and files: * bsps/shared/cache * bsps/@RTEMS_CPU@/shared/cache * bsps/@RTEMS_CPU@/@RTEMS_BSP_FAMILY/start/cache.c Update #3285.
