It's a generated config, see:

  https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/arch/powerpc/Makefile?commit=021c91791a5e7e85c567452f1be3e4c2c6cb6063#n315


It's based on pseries_defconfig, which is an actual file in the tree,
but with the endian flipped.

You can see the generated result from a recent build here:

cheers
