You shouldn't need to do all of this; only the xparameters_ml40x.h
file is needed. To get started, I'd just use replace
xparameters_ml403.h with your custom xparameters_ml40x.h and use the
ml403 board port. Once you've got it booting, you can get more fancy.

Make sure you've got 16550 console support enabled and
'console=/dev/ttyS0' in your kernel command line.
