From mboxrd@z Thu Jan 1 00:00:00 1970 From: magnus.damm@gmail.com (Magnus Damm) Date: Wed, 24 Jul 2013 16:27:39 +0900 Subject: [PATCH] ARM: shmobile: sh73a0: Rely on DT for SMP CPU info Message-ID: <20130724072739.28333.44251.sendpatchset@w520> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org From: Magnus Damm Remove sh73a0 specific ->smp_init_cpus() callback and instead of relying on shmobile_smp_init_cpus() simply use DT for CPU core information. This assumes that DT_MACHINE_START is used which is the case when AG5EVM and Kota2 are removed.
