CONFIG_BOOT_DELAY

This option delays bootup for the specified amount of milliseconds. This is used to allow serial ports to get ready before starting to print information on them during boot, as some systems might boot to fast for a receiving endpoint to detect the new USB serial bus, enumerate it and get ready to receive before it actually gets data. A similar effect can be achieved by waiting for DCD on the serial port–however, not all serial ports have DCD.
