    Subject[PATCH 4.19 134/247] powerpc/47x: Disable 256k page size
    Date
    From: Christophe Leroy <christophe.leroy@csgroup.eu>

    [ 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")
