From cb73cf4299a192e6065d567fae700987c3f937aa Mon Sep 17 00:00:00 2001 From: Richard Purdie Date: Fri, 20 Jan 2012 15:50:59 +0000 Subject: lib/oe: Add sstatesig, OE specific signature generator classes This patch adds SignatureGenerator classes specific to OE. For now, these emulate the previous behaviour with the exception that dependencies on quilt-native are now ignored for checksum purposes. The intent is to allow easier experimentation and customisation of this code in future as a result of these changes. Note that these changes require pending bitbake patches.
