The CTCU device for monaco shares the same configurations as SA8775p. Add a fallback to enable the CTCU for monaco to utilize the compitable of the SA8775p.

The Trace Memory Controller(TMC) is used for Embedded Trace Buffer(ETB),
|
|
Embedded Trace FIFO(ETF) and Embedded Trace Router(ETR) configurations.
|
|
The configuration mode (ETB, ETF, ETR) is discovered at boot time when
|
|
the device is probed.
|
|
|
|
The Coresight TMC Control unit controls various Coresight behaviors.
|
|
It works as a helper device when connected to TMC ETR device.
|
|
It is responsible for controlling the data filter function based on
|
|
the source device's Trace ID for TMC ETR device. The trace data with
|
|
that Trace id can get into ETR's buffer while other trace data gets
|
|
ignored.
