True, indeed it is hand written code sequence that we do for the
normal CoreSight components. The access to the components looks a bit
convoluted. However, with the coresight_access abstraction we have,
it is possible to abstract it away and move the driver framework to
CoreSight drivers.

Nothing that we could do at the moment without support from the
habana labs folks.
