From 2f2577a30f2a6b903e15ede7a7962e876fcad618 Mon Sep 17 00:00:00 2001 From: "Huang, Tao" Date: Thu, 1 Jun 2017 18:42:13 +0800 Subject: [PATCH] ARM: rockchip: enable ZONE_DMA for non 64-bit capable peripherals Most IP cores on ARM Rockchip platforms can only address 32 bits of physical memory for DMA. Thus ZONE_DMA should be enabled when LPAE is activated.
