From acc84707d3487735fc666fdeab76185d086428c0 Mon Sep 17 00:00:00 2001 From: Marek Szyprowski Date: Thu, 20 May 2010 07:51:08 +0200 Subject: ARM: SAMSUNG: move S5PC100 support from plat-s5pc1xx to plat-s5p framework This patch moves S5PC100 SoC support to plat-s5p framework. Most periperal support code has been already moved from plat-s5pc1xx to mach-s5pc100.

The driver needs to be aware on which SoC it is running, so the actual device id is being changed in cpu init code. S3C64xx SoCs have 2 OneNAND controllers while S5PC100 and S5PC110 has only one.
