FreeBSD on PPC embedded on Xilinx FPGA

  At the moment, no.

  Virtex 4/5 parts have 405-based hardcores, which FreeBSD doesn't yet 
support. The Virtex 6 will support 440-based cores, which FreeBSD does 
support on Freescale parts. It would still be some work to support 
Xilinx's soft-IP peripherals.

  I have a Virtex 4 with a 405 hard core, as well as an IBM Walnut 405 
eval, so with the recent work by Rafal and co on getting U-boot support 
for FreeBSD, maybe something will finally happen on the 405 front.

later,

Peter.
