This command is supported only by v1 images and specifies a milliseconds delay after executing some set of DATA commands. The special string value SDRAM_SETUP instructs BootROM to setup SDRAM controller instead of executing delay. SDRAM_SETUP may be specified only once and after the last DATA command.
