Subject: i.MX3: make SoC devices globally available
X-Git-Tag: v2.6.28-rc1~293^2~5^2~12
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=5cf0942123bcacf8af8922eaf3fef70bce6078e6;p=karo-tx-linux.git

i.MX3: make SoC devices globally available

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