Subject: [PATCH] ARM: shmobile: sh73a0: Rely on DT for SMP CPU info
Date: Wed, 24 Jul 2013 07:27:39 +0000 [thread overview]
Message-ID: <20130724072739.28333.44251.sendpatchset@w520> (raw)
From: Magnus Damm <damm@opensource.se>
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.
