Subject: board_f: Use static print_cpuinfo if CONFIG_CPU is active
X-Git-Tag: v2018.11-rc1~115^2~13
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=c0434407b595f785fc7401237896c48c791b45fd;p=oweals%2Fu-boot.git

board_f: Use static print_cpuinfo if CONFIG_CPU is active

When the DM CPU drivers are active, printing information about a CPU
should be delegated to a matching driver.

Hence, add a static print_cpuinfo that implements this delegation when
DM CPU drivers are active.
