Subject: MIPS: Netlogic: Initialization when !CONFIG_SMP
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=571886b2a52395f030d439c6259663a033e11e6a;p=openwrt%2Fstaging%2Fblogic.git

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
