In it's current form the TMC probe() function allocates trace buffer memory at boot time, event if coresight isn't used. This is highly inefficient since trace buffers can occupy a lot of memory that could be used otherwised. This patch allocates trace buffers on the fly, when the coresight subsystem is solicited. Allocated buffers are released when traces are read using the device descriptors under /dev.
