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.
