1540 While loading from serial is slow it can be a useful backup when
1541 there is no other option. The Ymodem protocol provides a reliable
1542 means of transmitting U-Boot over a serial line for using in TPL,
1543 with a checksum to ensure correctness.

1551 help
1552 Use external 8 to 24 Mhz clock signal as source of main clock instead
1553 of an external crystal oscillator.
1554 This option disables the internal driving on the XOUT pin.
1555 The external source has to provide a stable clock on the XIN pin.
1556 If this option is disabled, the SoC expects a crystal oscillator
1557 that needs driving on both XIN and XOUT lines.
