From a25de7af340fcd19a59978ded2ff04ed329bca06 Mon Sep 17 00:00:00 2001 From: Alexey Kardashevskiy Date: Tue, 16 Oct 2018 13:34:09 +1100 Subject: [PATCH] powerpc/powernv/ioda: Reduce a number of hooks in pnv_phb fixup_phb() is never used, this removes it. pick_m64_pe() and reserve_m64_pe() are always defined for all powernv PHBs: they are initialized by pnv_ioda_parse_m64_window() which is called unconditionally from pnv_pci_init_ioda_phb() which initializes all known PHB types on powernv so we can open code them.
