|
|
50 // Description: The macros defined here provide the platform specific |
|
|
51 // cache control operations / behavior. |
|
|
52 // Usage: Is included via the architecture cache header: |
|
|
53 // #include <cyg/hal/hal_cache.h> |

63 // FIXME: This definition forces the IO flash driver to use a |
|
|
64 // known-good procedure for fiddling flash before calling flash device |
|
|
65 // driver functions. The procedure breaks on other platform/driver |
|
|
66 // combinations though so is depricated. Hence this definition. |
|
|
67 // |
|
|
68 // If you work on this target, please try to remove this definition |
|
|
69 // and verify that the flash driver still works (both from RAM and |
|
|
70 // flash). If it does, remove the definition and this comment for good |
|
|
71 // [and the old macro definition if this happens to be the last client |
|
|
72 // of that code]. |
