Subject: powerpc, timer: Does 8xx specific actions in 8xx cpu_init
X-Git-Tag: v2017.09-rc1~153
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=93e85d02b21cdcd431df2237b883218f5c4059af;p=u-boot

powerpc, timer: Does 8xx specific actions in 8xx cpu_init

The actions inside #ifdef CONFIG_8xx in arch/powerpc/lib/time.c
can be performed before, in a 8xx dedicated function.
