From 5d5ef32ee4d102c38014057de4f283f18eee263b Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Tue, 24 Jan 2017 14:33:20 +0000 Subject: stellaris: Use the 'unimplemented' device for parts we don't implement Use the 'unimplemented' dummy device to cover regions of the SoC device memory map which we don't have proper device implementations for yet.
