/*******************************************************************************
* mvDramIfDetect - Prepare DRAM interface configuration values.
*
* DESCRIPTION:
*       This function implements the full DRAM detection and timing 
*       configuration for best system performance.
*       Since this routine runs from a ROM device (Boot Flash), its stack 
*       resides on RAM, that might be the system DRAM. Changing DRAM 
*       configuration values while keeping vital data in DRAM is risky. That
*       is why the function does not preform the configuration setting but 
*       prepare those in predefined 32bit registers (in this case IDMA 
*       registers are used) for other routine to perform the settings.
*       The function will call for board DRAM SPD information for each DRAM 
*       chip select. The function will then analyze those SPD parameters of 
*       all DRAM banks in order to decide on DRAM configuration compatible 
*       for all DRAM banks.
*       The function will set the CPU DRAM address decode registers.
*       Note: This routine prepares values that will overide configuration of
*       mvDramBasicAsmInit().
*       
* INPUT:
*       forcedCl - Forced CAL Latency. If equal to zero, do not force.
*
* OUTPUT:
*       None.

*       None.
