Subject: [U-Boot] [PATCH] armv7 cpu_init_crit: Simplify code
Date: Sat, 11 Aug 2012 00:05:16 +0200 (CEST) [thread overview]
Message-ID: <2025492723.2284420.1344636316297.JavaMail.root@advansee.com> (raw)
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.
