7	  Say Y here to include definitions of printascii, printch, printhex
8	  in U-Boot.  This is helpful if you are debugging code that
9	  executes before the console is initialized.

17		help
18		  Say Y here if you wish the debug print routes to direct
19		  their output to an 8250 UART.  You can use this option
20		  to provide the parameters for the 8250 UART rather than
21		  selecting one of the platform specific options above if
22		  you know the parameters for the port.
23
24		  This option is preferred over the platform specific
25		  options; the platform specific options are deprecated
26		  and will be soon removed.
