From 9425a545d777f611214731f92220692d9e6aedd7 Mon Sep 17 00:00:00 2001 From: Aaron Durbin Date: Tue, 7 Oct 2014 23:36:55 -0500 Subject: libpayload arm64: fix mmu bugs 1. keep functions and objects used entirely within mmu.c as static. 2. DMA region finding needs to terminate. Therefore, the next address to be attempted needs to be less then the current end address. 3. Ensure mmu_ranges passed to mmu_init_ranges_from_sysinfo() has 0 entries marked as used. BUG=chrome-os-partner:31634 BRANCH=None TEST=Booted ryu with RAM hole above cbmem tables below 4GiB.
