This is the wrong level for BSP-specific options. You have to look for:

Actually, it would be nice if all BSPs use the same option for this 
setting. However, this requires that someone has the time to convert all 
console drivers to use this option. Also the removal of the old build 
system is required for cleanup work like this.
