From feb8fa2ef0a5ff6627baac749a72dfaa15e37714 Mon Sep 17 00:00:00 2001 From: Alison Wang <alison.wang@nxp.com> Date: Tue, 21 Jan 2020 07:33:01 +0000 Subject: [PATCH] configs: ls1021a: Reserve low memory for CMA The default reserved memory for CMA is high memory. If LPAE is enabled, highmem pages are non-remapped and can not be used with dma_alloc_coherent. This patch will reserve low memory for CMA and fix the issue on LS1021A.
