help
Say Y here to include definitions of printascii, printch, printhex
in the kernel. This is helpful if you are debugging code that
executes before the console is initialized.
Note that selecting this option will limit the kernel to a single
UART definition, as specified below. Attempting to boot the kernel
image on a different platform *will not work*, so this option should
not be enabled for kernels that are intended to be portable.

Say Y here if your platform doesn't provide a UART option
below. This relies on your platform choosing the right UART
definition internally in order for low-level debugging to
work.
config DEBUG_ICEDCC
bool "Kernel low-level debugging via EmbeddedICE DCC channel"
help
Say Y here if you want the debug print routines to direct
their output to the EmbeddedICE macrocell's DCC channel using
co-processor 14. This is known to work on the ARM9 style ICE
channel and on the XScale with the PEEDI.
Note that the system will appear to hang during boot if there
is nothing connected to read from the DCC.
