Hey:
    Recently I'm doing some project on Xilinx Ml410 evaluation board.The
first step is porting linux 2.6 to ml410,but I got some problems on this,and
my project cann't proceed,so I come to you for some help.
    I use the linux kernel source tree download from
http://git.secretlab.ca/git/linux-2.6-virtex.git  (The
latest one).Add the file the xparameters.h,xparameter_ml40x.h.  Then add
arch/ppc/platforms/4xx/xilinx_generic_ppc.c(Use the patch I
get here),and change it's name to ml40x.c,then I make some necessay change
of the configuration files to accept selecting a Ml40x type board.

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.

Then
compile the kernel,and get the image file from arch/ppc/boot/images, (On
kernel compiling,the only device driver  I sellect is " 8250/16550 and
compatible serial support ").After that  I download the zImage.elf file to
the target board,and run it.But there is no output from the serial port at
all.Am I doing somthing wrong?I really don't know goes wrong.
    Can anyone here help me with this?Any help from you is appreciated.Thank
you very much!

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

Cheers,
g.
