-* mvVrtBrgPexInit - Initialize PEX interfaces
-*
-* 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
-*
