Due to list size limitations, I have sent a patch directly to Wolfgang 
Denk which add support for a custom Virtex2Pro FPGA (PPC405) based ant2 
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
