Hi All,
I am really clueless about this. The board manufacturer (ARM926EJ-S) suggests that its Fast Ethernet MAC is a dec21140/21143 clone. However, the board only has MII interface on its MAC Control Register. This means that it's dec21143 clone only provides MII interfaces. The MAC Control Registers have somewhat similar interfaces with the MII ports of the dec21143. Now, please help me with these:
1. Are there direct mapping of the PCI Control Registers of the dec21143 to its MII Interfaces? I was trying to make sense of the dc21143.c driver's PCI interfaces with MII interfaces, but I could not make any useful information from it.
2. Are there minimal configuration routines for MII interfaces similar to dec21143?
Thank you very much for your time.
Best Regards,
Rodel
