I noticed that in SDK 1.6 3.12 kernel was used. It will be the same in SDK 1.7?

[Luo Zhenhua-B19537] Due to the release time gap of Yocto(Apri/Oct) and QorIQ SDK(Jun/Dec), so QorIQ SDK 1.6(2014-Jun) content will be in Yocto 1.7(2014-Oct), the QorIQ SDK 1.7(2014-Dec) content will be included in Yocto 1.8(2015-Apr).
