DDR_SDRAM_MODE2 register. If software is initializing memory, then the MEM_HALT bit can be
set to prevent the DDR controller from issuing transactions during the initialization sequence.
Note that the DDR controller will not issue a DLL reset to the DRAMs when bypassing the
initialization routine, regardless of the value of DDR_SDRAM_CFG[DLL_RST_DIS]. If a DLL
reset is required, then the controller should be forced to enter and exit self refresh after the
controller is enabled.
