From 55b0a375eaf32728573e3c852d8712267e5c7812 Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Sun, 5 Dec 2010 21:53:18 +0100 Subject: linux: support a space-separated list of patches The kernel being a component that often needs a fairly important set of changes to be adapted to a particular hardware platform, having maximum flexibility on the patching process is a nice thing. Therefore, as per the discussions from the Buildroot Developer Day, we add a mechanism to apply a list of patches (that could come either from URLs, local files or local directories).
