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.
