File 0009-Revert-armv8-Enable-CPUECTLR.SMPEN-.patch of Package u-boot-cubieboard2
From 607baf77917bf079758ec6d60abf283cc701638c Mon Sep 17 00:00:00 2001 From: Tom Rini <trini@konsulko.com> Date: Thu, 14 Jul 2016 17:36:18 -0400 Subject: [PATCH] Revert "armv8: Enable CPUECTLR.SMPEN for coherency" MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Upon further review this breaks most other platforms as we need to check what core we're running on before touching it at all. This reverts commit d73718f3236c520a92efa401084c658e6cc067f3.
