Cache.c contains code to correctly flush instruction and data caches on all Macintosh CPUs.
Beginning with the Macintosh II, developers were faced with situations where instruction and/or data caches needed to be flushed for code to execute correctly. Unfortunately, despite recent improvements (i.e. _HWPriv, see Tech Note #261), cache flushing remains highly CPU and system specific and developers have had difficulty doing it in a way the ensures both forward and backward compatibility. Cache.c contains a single function call that will work across all platforms, yet still provides access to such advanced MC68040 features as selective cache range flushing.
