*				Bar2 is always the Device bar
*
*  1) Sets the Internal registers bar base by obtaining the base from

*  2) Sets the DRAM bar base and size by getting the base and size from
*     the CPU Interface when the size is the sum of all enabled DRAM 
*	  chip selects and the base is the base of CS0 .
*  3) Sets the Device bar base and size by getting these values from the 
*     CPU Interface when the base is the base of the lowest base of the
*     Device chip selects, and the
