From 98d1c7d83485ed2b024bf8ab5f8ff7e2a66ab85e Mon Sep 17 00:00:00 2001 From: Paul Spooren Date: Mon, 4 Nov 2019 10:55:23 -1000 Subject: [PATCH] build: image: add common and reproducible IMG_PART_SIGNATURE variable MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit x86, mvebu and tegra targets are currently using more or less same SIGNATURE variable which provides unique partition ID/signature, so it makes sense to refactor it out into common variable which could be reused by all targets. While at it, make the content of the variable reproducible.
