From db756327f5c765457514b005f70624c6f81688cf Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Fri, 24 Aug 2018 14:35:17 +0200 Subject: [PATCH] rauc: add patch to make it build with Linux < 3.0 This commit adds a patch to RAUC that makes the eMMC boot partition support optional. This allows RAUC to build successfully on systems using Linux < 3.0.
