From fa1392a236dfebbe938a48f124c8332759aba8e5 Mon Sep 17 00:00:00 2001 From: Kever Yang Date: Thu, 20 Apr 2017 17:03:46 +0800 Subject: rockchip: reserve memory for rk3399 ATF data There are 3 regions used by rk3399 ATF: - bl31 code, located at 0x10000; - cortex-m0 code and data, located at 0xff8c0000; - bl31 data, located at 0xff8c1000 ~ 0xff8c4000; SPL_TEXT_BASE starts from 0xff8c2000, we need to reserve memory for ATF data, or else there will be memory corrupt after SPL loads the ATF image.
