Subject: armv7 cpu_init_crit: Simplify code
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=63ee53a7e9f5ec38e6a8e485d2b5f0119ff1c6d1;p=project%2Fbcm63xx%2Fu-boot.git

armv7 cpu_init_crit: Simplify code

We don't need to return to cpu_init_crit after calling lowlevel_init, so
lowlevel_init can directly return to the caller of cpu_init_crit.
