Say Y here to include definitions of printascii, printch, printhex
|

|
|
in U-Boot. This is helpful if you are debugging code that
|

|
|
executes before the console is initialized.

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