If you look at the ddr register programming aid spreadsheet you will see how the MRn registers are written to MDSCR. The top 16 bits contain the desired MRn values and the bottom are the command and address of which MR register to write. In the example I am looking at the 32 bit value is 0x00048031 the 0x0004 is the MR1 value and the bottom bits are 3 for load mode register and 1 for MR1. So long story short the 0x4 is the right value.
