I didn't want to enable it if no one is using it at the moment. But, I took me long enough to figure out how to enable the Static memory Controller in the MMU with out any hints to begin with. Also the EBI portion is present in a vendor kernel version 2.6.21. The Static Memory Controller peripheral needs to be set when ethernet chips like the dm9000 is attached to the samsung ARM S3C2416. The Boardcon board is a good example.
