Is there any value in building for -mcpu=440 or -mcpu=464 when targeting a 476?
Maybe add another !PPC_47x dependency for the first two. Ideally we would also
enforce that 440/464 based boards cannot be selected together with 476, though
I guess that is a separate issue.
Is there a practical difference between 440 and 464 when building kernels?
gcc seems to treat them the same way, so maybe one option for both is enough
here.
