Hello,

I'm glad to announce that port to ibm405 core embedded
in Xilinx Virtex {2-Pro, 4 FX} series FPGAs is now
available:

  ftp://koza.uamt.feec.vutbr.cz/pub/jh/virtex.diff
  ftp://koza.uamt.feec.vutbr.cz/pub/jh/virtex-gsrd-edk.tar.bz2

  [this is tempory location, may suffer downtime]

The code is primarily targeted at Xilinx's GSRD reference
design [1] on a ML403 (Virtex 4 FX chip) board, although
it is capable of running on a custom Virtex 2-Pro board
too (in a minimal setup) and adaptation for custom FPGA
designs is expected to be more or less SMOP.

Drivers (see [2]):

  * cdmac: DMA controller, interfaces to MPMC memory
    controller on one side and to LocalLink channels
    on the other

  * temac: gigabit ethernet core, MAC is hard-core
    inside the Virtex 4, DMA transfers are handled
    via LocalLink to the cdmac

  * xlcom: UartLite serial port
