OK, Thanks for the clarification.

The CONFIG_EDAC_ALTERA_MC is a little confusing because it refers to the 
Memory Controller (SDRAM) and uses that in the menu string(Altera SDRAM 
Memory Controller EDAC).

Would it be confusing to rename this CONFIG_EDAC_ALTERA, update the 
SDRAM code to check the ECC Enable bit instead of this config option and 
update the string in the menu?

I'll keep this as one file and implement your suggested changes and 
resubmit.
