| ** It is supposed these functions to be used for a low level |

| ** Unfortunately Cayman LEDs relies on Cayman EPLD to be mapped |
| ** (this happen when IRQ are initialized... quite late). |
| ** These triky dependencies should be removed. Temporary, it |
| ** may be enough to NOP until EPLD is mapped. |
