Subject: linux-yocto: locate and use out of tree features specified on the SRC_URI
X-Git-Tag: rev_ivi_2015_02_04~18789
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=ec73317bfeae7418d2468d38b516bc57815ab78e;p=scm%2Fbb%2Ftizen-distro.git

linux-yocto: locate and use out of tree features specified on the SRC_URI

In a similar manner to calling the patch.bbclass to locate patches that
were listed on the SRC_URI, it is also useful to query about 'other' items
that are on the SRC_URI. In the case of linux-yocto, it allows us to
know about kernel features that were specific on the URI and then apply
them to the current tree.
