From 762e79dfb769e885758bdcc627fadbe4dc6454fd Mon Sep 17 00:00:00 2001 From: Paul Eggleton Date: Fri, 14 Aug 2015 12:15:08 +0100 Subject: classes/whitelist: add class to allow whitelisting recipes from a layer Allow restricting recipes brought from a layer to a specified list. This is similar in operation to blacklist.bbclass, but instead specifies a per-layer whitelist of recipes (matched by PN or BPN) that are able to be built from the layer - anything else is skipped. This is potentially useful where you want to bring in a select set of recipes from a larger layer e.g. meta-oe. Implements [YOCTO #8150].
