* The PTI (Parallel Trace Interface) driver directs trace data routed from |
|
* various parts in the system out through the Intel Penwell 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. |
|
* |
|
* 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. |
