From: Chen Ganir <chen.ganir@xxxxxx>
Texas Instruments controllers can be configured to send the
internal firmware log through a vendor specific HCI event on
the hci transport.
This patch allows capturing those log events, and writing them
to a file, which can then be used with the latest TI Logger
application to read and show the logs.
This is usefull in case there is no other way to get the TI log
(for example, the lack of a connection to the controller Log TX
hardware line).
