CONFIG symbols that are hardware parameters rather than user-tweakable 
config go in the CONFIG_SYS namespace (see "Software Configuration" in 
README).

I think it should also be an FSMC-specific parameter, not something that 
looks universal.

The struct name takes that role here; hardware documentation doesn't 
have the benefit of that.
