From e61a7534e33063a76e105d895e5c6317f2d0cd76 Mon Sep 17 00:00:00 2001 From: York Sun Date: Fri, 24 Jun 2016 16:46:18 -0700 Subject: [PATCH] armv8: Move secure_ram variable out of generic global data Secure_ram variable was put in generic global data. But only ARMv8 uses this variable. Move it to ARM specific data structure.
