config DEBUG_LL
bool "Low-level debugging functions"
depends on !ARM64
help
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.

prompt "Low-level debugging port"
depends on DEBUG_LL
config DEBUG_LL_UART_8250
bool "Low-level debugging via 8250 UART"
help
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.
