| 1 /* | |
| 2 * This module is a FreeCalypso addition for very low-level debugging. | |
| 3 * The functions implemented in this module produce "forced" serial output | |
| 4 * on the RVTMUX UART without going through the normal RV trace mechanism. | |
| 5 * Calls to these FC debug functions should be added during difficult | |
| 6 * debug sessions, but should never remain in stable checked-in code: | |
| 7 * these functions are too disruptive to be used in "production" fw images. | |
