From 566ce04de4a2b4c66be8e13751dbb0bfe80117b3 Mon Sep 17 00:00:00 2001 From: Paul Burton Date: Wed, 21 Sep 2016 11:18:56 +0100 Subject: [PATCH] MIPS: Malta: Enable CM & L2 support Enable support for the MIPS Coherence Manager & L2 caches on the MIPS Malta board, removing the need for us to attempt to bypass the L2 during boot (which would fail with recent CPUs that expose L2 config via the CM anyway).
