As this doesn't appear to be a complete driver, why is it
user-selectable? Likewise for the other flib patches.
Why are you adding the flibs in a big batch, rather than bundling the
code with the driver patches that use it?
Is there a minimal core of fman functionality (complete functionality,
not flibs) that you could start with, rather than trying to get the
entire thing reviewed at once? In other words, break it up vertically,
not horizontally.
Note that the lack of caller context is especially harmful given that
the functions are not documented.

You won't even get into this makefile if CONFIG_FSL_FMAN=n... Did you
really mean to exclude this stuff when CONFIG_FSL_FMAN=m?

Without seeing the caller, I can't judge whether there's a good reason
for passing this in by number rather than passing in FPM_RSTC_MACn_RESET
directly and avoiding the switch.
