From bacf9cf88303c0df5794ca45dd9f297740a00913 Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Tue, 26 Jul 2016 21:31:59 +1000 Subject: powerpc/mm: Do hash device tree scanning earlier Currently MMU initialisation (early_init_mmu()) consists of a mixture of scanning the device tree, setting MMU feature bits, and then also doing actual initialisation of MMU data structures. We'd like to decouple the setting of the MMU features from the actual setup. So split out the device tree scanning, and associated code, and call it from mmu_init_early_devtree().
