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

Brad,
I've uploaded a zip file that contains FPGA designs for ML300, ML310, ML403 and ML410 as well as an U-Boot snapshot with all "Xilinx" patches included to ftp://customer:xilinx@ftp.xilinx.com/upload/xapp542.zip (12 MB)
The design for the ML403 maps the Flash at the reset vector. I have several ML403s that completely boot from linear flash - bitstream, U-Boot, Linux kernel. I've enabled MTD support in the Linux kernel. With that I can upgrade bitstream and Linux image from within Linux.
As you can see from the name the uploaded zip file is part of a project to update the current Xilinx application note XAPP542 with a newer version. I'm kind of been waiting for the September patches to be applied in the U-Boot CVS but figured Wolfgang must be busy with other stuff as I was myself.

Wolfgang,
Were the Xilinx patches (2005-09-28 thru 2005-10-02) rejected or lost, or are they still in your queue?
Peter,
Do you happen to have a design for the ML403 that boots directly from the linear flash? Perhaps with devices mapped as in board/xilinx/ml403/xparameters.h? It would be easier to start with a design known to work with U-Boot.
Thanks,
