From 42082f7c23ded282489e8ac6ec52fe94fa097cde Mon Sep 17 00:00:00 2001 From: Antonio Borneo Date: Mon, 22 Nov 2010 12:21:31 +0800 Subject: [PATCH] FLASH/NOR: rename from spearsmi to stmsmi STMicroelectronics controller SMI is not SPEAr specific. Rename it and change name to every symbol in the code.
