From c20b4dd31820a551d0fb60bf27b99345905c2eb6 Mon Sep 17 00:00:00 2001 From: Christian Glindkamp Date: Thu, 9 Dec 2010 11:15:59 +0100 Subject: at91: Refactor Stamp9G20 and PControl G20 board file As PControl G20 is a carrier board for the Stamp9G20 SoM, some code can be shared. Therefore board-stamp9g20.c is refactored to allow reusing the SoM initialization and board-pcontrol-g20.c is modified to use it.
