From 33893d7aa00057d067527e0d8c210190efade8f1 Mon Sep 17 00:00:00 2001 From: Magnus Damm Date: Thu, 6 Aug 2009 14:58:43 +0000 Subject: sh: kfr2r09 board support - NAND flash This patch adds support for the NAND flash chip attached to CS4 on the KFR2R09 board. The device is driven by the platform device driver "onenand-flash".
