From d521f87e9c642dbc820cb839039e25a05cb02151 Mon Sep 17 00:00:00 2001 From: Ben Dooks Date: Tue, 21 Oct 2008 14:06:40 +0100 Subject: [ARM] S3C64XX: Initial arch header files Add the initial header files for the S3C64XX support to satisfy the minimal requirements to build a kernel. Some definitions will therefore be placeholders or empty functions that will ensure that the system can build and have base functionality. These will be filled in at a later date.
