From 95d59741d281a64eba60c3283827b73680849770 Mon Sep 17 00:00:00 2001 From: Pawel Moll Date: Fri, 24 Feb 2012 09:18:14 +0000 Subject: ARM: vexpress: Use FDT data in platform SMP calls Scan flatten device looking for A5/A9 SCU node and initialize it using base address in "reg" property. If nothing is found, assume that there is no special SCU initialization required and initialize CPUs basing on numbers of "cpu" type devices in "cpus" node of the Device Tree. All this happens only if the board was booted with FDT, otherwise ct_desc callbacks are used.
