From 4b3e6f2ef3722f1a6a97b6034ed492c1a21fd4ae Mon Sep 17 00:00:00 2001 From: Max Filippov Date: Tue, 31 Jan 2017 18:35:37 -0800 Subject: xtensa: fix noMMU build on cores with MMU Commit bf15f86b343ed8 ("xtensa: initialize MMU before jumping to reset vector") calls MMU management functions even when CONFIG_MMU is not selected. That breaks noMMU build on cores with MMU. Don't manage MMU when CONFIG_MMU is not selected.
