Summary	0002443: Serial overflow results in off-by-one error on serial line
Description	When U-Boot starts and gets more than 8 characters on the serial line as input before the command line is active, the serial communication has a displacement of one. This means that when a character is typed on the command line, the previous character is echoed instead.
Steps To Reproduce	When U-Boot starts, there is a small delay after the NAND memory size is output and before the MMC is detected. Test 1: Type a single character in this pause. Everything is OK, command line input is correct. Test 2: Press a key until it repeats. Now start the board. This results in sending more than 8 characters to the board in this pause above. Now the input on the command line is off by one.
