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