Why do we need separate patches just for headers?

What does "common" refer to?

What does the flib directory mean, in the context of Linux?  If 
someone were to add code to this driver, how do they know if the code 
should go into the flib directory or not?

iowrite32be()/ioread32be() are already defined for all relevant 
architectures.  Why are you redefining them into something PPC-
specific?
