Porting DE_NET2 to NIOSII running on Quartus 12.1sp1 and QSYS

Hi,

I was able to make it running.

I have made no changes to NIOS code except changing this define:

#define IO_data     4

Also in the code the DM9000A.C file was included, which is rather bad so I only included .h file

and had to move ether_addr table to .C file from .h.

In my DM9000A component i have changed iDATA and oDATA to 32 bit and simply assigned

lower 16 bits to ENET_DATA.

I also resized iCMD to 8 bits and found out that bit 4 goes up when I write.

So i simply assigned this bit to ENET_CMD.

Also I changed read wait and write wait to 3 clock cycles in my DM9000A component (it's related to 100MHz clock for NIOS).

Best,

madness
