Could you please help to give some suggestions?

During DDR initialization, I set D_INIT and loop to polling this bit, it will be cleared. Does it mean that the DDR can be initialized by itself. But at this time, I only can access a little address space of DDR, I guess it is accessing cache, not really access DDR, since when I try to read a larger for example 4M address space of DDR, it will fail.
