+/* Initialization path:
+ * We expect that acceleration initialization might fail for various
+ * reasons even thought we work hard to make it works on most
+ * configurations. In order to still have a working userspace in such
+ * 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
+ * memory controller (only MC setup failure
+ * are considered as fatal)
