From 334973bbae19788559f940966c8e3a208edbb1ee Mon Sep 17 00:00:00 2001 From: Andrew Jeffery Date: Mon, 27 Jun 2016 15:37:33 +0100 Subject: ast2400: Integrate the SCU model and set silicon revision MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit By specifying the silicon revision we select the appropriate reset values for the SoC. Additionally, expose hardware strapping properties aliasing those provided by the SCU for board-specific configuration.
