From bcae8aeb320dfe8dde4b3512237a5b76737b0120 Mon Sep 17 00:00:00 2001 From: Ben Dooks Date: Tue, 21 Oct 2008 14:06:32 +0100 Subject: [PATCH] [ARM] S3C24A0: Initial architecture support files Initial architecture support for the S3C24A0 ARCH_S3C24A0. We don't yet add an kconfig entry in the main arch/arm/Kconfig file as the series is not complete, so that is left until enough support is in to be useful.
