| 1490 | While loading from serial is slow it can be a useful backup when |
| 1491 | there is no other option. The Ymodem protocol provides a reliable |
| 1492 | means of transmitting U-Boot over a serial line for using in TPL, |
| 1493 | with a checksum to ensure correctness. |

| 1502 | Use external 8 to 24 Mhz clock signal as source of main clock instead |
| 1503 | of an external crystal oscillator. |
| 1504 | This option disables the internal driving on the XOUT pin. |
| 1505 | The external source has to provide a stable clock on the XIN pin. |
| 1506 | If this option is disabled, the SoC expects a crystal oscillator |
| 1507 | that needs driving on both XIN and XOUT lines. |
