bool "Early printk"
optional
help
You may want to enable early printk if you are debugging code
that executes before the console is initialized.
Note that selecting this option will limit Xen to a single UART
definition. Attempting to boot Xen image on a different
platform *will not work*, so this option should not be enable
for Xens that are intended to be portable.
Choose one of the UART drivers for early printk, then you'll
have to specify the parameters, like the base address.
Deprecated: Alternatively, there are platform specific options
which will have default values for the various parameters. But
such option will soon be removed.
config EARLY_UART_CHOICE_8250
select EARLY_UART_8250
bool "Early printk via 8250 UART"
help
Say Y here if you wish the early printk to direct their
output to a 8250 UART. You can use this option to
provide the parameters for the 8250 UART rather than
selecting one of the platform specific options below 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 soon be removed.

Say Y here if you wish the early printk to direct their
