 * The SDM (System Debug Monitor) directs trace data routed from
 * various parts in the system out through the Intel Tangier PTI port and
 * out of the mobile device for analysis with a debugging tool
 * (Lauterbach, Fido). This is part of a solution for the MIPI P1149.7,
 * compact JTAG, standard and USB Debug-Class
 *
 * This header file will allow other parts of the OS to use the
 * interface to write out it's contents for debugging a mobile system.
