/* Initialization path:
* We expect that acceleration initialization might fail for various

* situation the init path must succeed up to the memory controller
* initialization point. Failure before this point are considered as
* fatal error. Here is the init callchain :
* radeon_device_init perform common structure, mutex initialization
* asic_init setup the GPU memory layout and perform all
* one time initialization (failure in this
* function are considered fatal)
* asic_startup setup the GPU acceleration, in order to
* follow guideline the first thing this
* function should do is setting the GPU
