Probably these two values comes from old Marvell DDR training code which was separated from U-Boot and used it for some configuration. Seems that two 32-bit values were specified here to ensure SPL code alignment to 128-bit boundary as it is required e.g. for A370 or AXP processors. Main kwbimage header is 64-byte long which is aligned to 128-bit boundary. Optional kwbheader is 32-bit long, number of BIN header arguments is stored in 32-bit number. So for alignment to 128-bit boundary is needed 64-bit padding which exactly these two 32-bit dummy arguments provided. Now when mkimage correctly aligns start of executable code in BIN header to 128-bit boundary, there is no requirement to put dummy argument values into kwbimage. So remove them.
