| |
WHY I"M ASKING THIS QUESTION: I'm implementing some gpio calls in the ep93xx arch. My problem is that gpio's are really board specific, not just mach specific. I can code the function calls into my board init, but where should these functions be prototyped?
Ideally, I think the compiler should build a "default" function for int gpio_request which fails, rather than a compile error for other boards within the same arch.
THE ACTUAL QUESTION: Is there a way to build a "default" function, which is compiled in if it's not defined elsewhere? Anyone know where an example of this might be lurking. Also, if this is possible, is it a good idea?
thx, NZG
