+// Purpose:     Platform cache control API
+// Description: The macros defined here provide the platform specific
+//              cache control operations / behavior.
+// Usage:       Is included via the architecture cache header:
+//              #include <cyg/hal/hal_cache.h>
+//

+// Initial cache enabling - controlled by common CDL

+// FIXME: This definition forces the IO flash driver to use a
+// known-good procedure for fiddling flash before calling flash device
+// driver functions. The procedure breaks on other platform/driver
+// combinations though so is depricated. Hence this definition.
+//
+// If you work on this target, please try to remove this definition
+// and verify that the flash driver still works (both from RAM and
+// flash). If it does, remove the definition and this comment for good
+// [and the old macro definition if this happens to be the last client
+// of that code].
