[PATCH 4.14 087/176] powerpc/47x: Disable 256k page size

[Greg Kroah-Hartman]

From: Christophe Leroy <christophe.leroy@xxxxxxxxxx>

[ Upstream commit 910a0cb6d259736a0c86e795d4c2f42af8d0d775 ]

PPC47x_TLBE_SIZE isn't defined for 256k pages, leading to a build
break if 256k pages is selected.

So change the kconfig so that 256k pages can't be selected for 47x.

Fixes: e7f75ad01d59 ("powerpc/47x: Base ppc476 support")
