From b033271f11a17debc1cc3e56f6b9fa319ebe2c45 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?C=C3=A9dric=20Le=20Goater?= Date: Thu, 22 Sep 2016 18:13:05 +0100 Subject: aspeed-soc: provide a framework to add new SoCs MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Let's define an object class for each Aspeed SoC we support. A AspeedSoCInfo struct gathers the SoC specifications which can later be used by an instance of the class or by a board using the SoC.
