From 85cc00eaa81dfa0f5bf8076c48f3ee2c2c4a77ba Mon Sep 17 00:00:00 2001 From: Lorenzo Pieralisi Date: Mon, 18 Nov 2013 18:56:42 +0000 Subject: arm64: kernel: add code to set cpu boot mode to secondary_entry shim The refactoring of el2_setup split code setting up EL2 and detecting the CPU boot mode in separate chunks. This allows the code that sets up EL2 to run in an endian independent way - ie before the endianess is set up in the respective sctlr registers. This patch brings secondary_entry up-to-date so that CPUs entering the kernel through this code path set-up EL2 and the cpu boot mode properly.
