Having these selected doesn't change how the kernel is compiled or how
the kernel uses the code which these provide.  These mainly control
which files are built.

They also control indirectly how the code is called - but the ultimate
decision is made by the CPU which is detected and the block in
__fa526_proc_info.

So, having these symbols enabled (provided the right ones for FA526 are
also enabled) makes no difference.  So I don't buy your explanation.
