From: Magnus Damm Date: Wed, 24 Jul 2013 07:27:39 +0000 (+0900) Subject: ARM: shmobile: sh73a0: Rely on DT for SMP CPU info X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=5489cde560f2b13dc9fb34e2d7dfd09a69fa21b1;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git ARM: shmobile: sh73a0: Rely on DT for SMP CPU info 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.
