Subject: i.MX3: make SoC devices globally available
X-Git-Tag: firefly_0821_release~17401^2~5^2~12
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=5cf0942123bcacf8af8922eaf3fef70bce6078e6;p=firefly-linux-kernel-4.4.55.git

i.MX3: make SoC devices globally available

Make SoC devices globally available to boards rather than using
a device specific init function.
