From 33c3dfd2976e0752e69c36b27b88809c9b4ada12 Mon Sep 17 00:00:00 2001 From: Alison Wang Date: Thu, 23 Apr 2020 22:37:34 +0800 Subject: [PATCH] configs: ls1021a: Append CMA configuration to bootargs 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. Reserving low memory for CMA is needed for LS1021A. This patch appends the related CMA configuration to bootargs.
