Hi Peter,

I have a Xilinx ML403 board and I'm trying to make u-boot start directly 
from linear flash.
I compiled U-Boot with your patches for ML403 and I tried to syntesize 
an EDK project starting with the reference desing and remapping the 
linear flash at the end of the memory space. By the way, when I 
configure the Virtex-4 with the generated bitstream the 'Error 1' led 
(the red one) turns on, so I've certainly made some mistake.
I found the following message in list and I try to download the linked 
.zip file, but the link seems to be broken.
Can I have the XPS files with the correct memory map and system 
configuration in order to run u-boot from flash?
There are other important things that I should know for make it working?
Than you

Filippo Capurso
