MIPS: Netlogic: Initialization when !CONFIG_SMP
The core initialization and reset vector setup needs to be done even when booting uniprocessor. Move this code from smp.c to setup.c Signed-off-by: Jayachandran C <jchandra@broadcom.com> Cc: linux-mips@linux-mips.org Patchwork: https://patchwork.linux-mips.org/patch/5428/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
