+* DESCRIPTION:
+*
+* This function is responsible of intialization of the Pex Interface , It
+* configure the Pex Bars and Windows in the following manner:
+*
+* Assumptions :
+* Bar0 is always internal registers bar
+* Bar1 is always the DRAM bar
+* Bar2 is always the Device bar
+*
+* 1) Sets the Internal registers bar base by obtaining the base from
+* the CPU Interface
+* 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
+*
+*
+* INPUT:
+*
+* pexIf - PEX interface number.
+*
+*
+* OUTPUT:
+* None.
+*
+* RETURN:
+* MV_OK if function success otherwise MV_ERROR or MV_BAD_PARAM
