 *	- WB : write back stuff (do it bit like scratch reg things)

/* 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)
