[U-Boot-Users] [PATCH] (Resend notice only) Add support for Xilinx Virtex2Pro based ant2 board

[Keith J Outwater]

I have sent a patch directly to Wolfgang Denk which adds support for a 
custom Virtex2Pro
FPGA (PPC405) based ant2 board. The patch has not been posted to the list 
due to list attachment
size limits. The board uses a Xilinx SystemACE to configure the FPGA and a 
Compact Flash card to
store FPGA configuration data.  The ant2 BSP stores all nonvolatile data 
on the CF card since the board
does not have any fixed (i.e. non-removable) nonvolatile memory. The CF 
card contains the FPGA
configuration bitstream, the kernel image, the root filesystem image, a 
default environment initialization script,
and the U-Boot bootloader image.  A small Initial Program Loader (IPL) is 
incorporated into the FPGA bitstream
and is placed into on-chip FPGA RAM at FPGA configuration.  The IPL loads 
the U-Boot image into main
memory and then transfers control.  This two stage scheme  reduces the 
FPGA on-chip RAM requirements
from approximately 256 KiB to approximately 25 KiB.
