From a8655e83fc44ec2b92cbea9f3ff3cc0da05a991c Mon Sep 17 00:00:00 2001 From: Catalin Marinas Date: Mon, 4 Feb 2008 17:30:57 +0100 Subject: [ARM] 4814/1: RealView: Add broadcasting clockevents support for ARM11MPCore This patch adds dummy local timers for each CPU so that the board clock device is used to broadcast events to the other CPUs. The patch also adds the declaration for the dummy_timer_setup function (the equivalent of local_timer_setup when CONFIG_LOCAL_TIMERS is not set). Due to the way clockevents work, the dummy timer on the first CPU has to be registered before the board timer.
