// Status signals changed, Adress decoding changed, interrupt controller
// added.
//
// Revision 1.2 2001/09/24 15:02:56 mohor
// Defines changed (All precede with ETH_). Small changes because some
// tools generate warnings when two operands are together. Synchronization
// between two clocks domains in eth_wishbonedma.v is changed (due to ASIC
// demands).
//
// Revision 1.1 2001/08/06 14:44:29 mohor
// A define FPGA added to select between Artisan RAM (for ASIC) and Block Ram (For Virtex).
// Include files fixed to contain no path.
// File names and module names changed ta have a eth_ prologue in the name.
// File eth_timescale.v is used to define timescale
// All pin names on the top module are changed to contain _I, _O or _OE at the end.
// Bidirectional signal MDIO is changed to three signals (Mdc_O, Mdi_I, Mdo_O
// and Mdo_OE. The bidirectional signal must be created on the top level. This
// is done due to the ASIC tools.
//
// Revision 1.1 2001/07/30 21:23:42 mohor
// Directory structure changed. Files checked and joind together.
//
