From 74af4eec29f828b8ddf51d9f071264866c868ccb Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?C=C3=A9dric=20Le=20Goater?= Date: Tue, 27 Dec 2016 14:59:27 +0000 Subject: aspeed: add a memory region for SRAM MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The size of the SRAM depends on the SoC model, so use a per-soc definition when creating the region.
