From mboxrd@z Thu Jan 1 00:00:00 1970 From: pavel@denx.de (Pavel Machek) Date: Wed, 18 Jul 2012 12:25:08 +0200 Subject: [PATCH v4] arm: socfpga: Add initial support for Altera's SOCFPGA HW Message-ID: <20120718102507.GA11993@elf.ucw.cz> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org From: Dinh Nguyen Adding core definitions for Altera's SOCFPGA ARM platform. Signed-off-by: Dinh Nguyen Reviewed-by: Pavel Machek Reviewed-by: Rob Herring Signed-off-by: Pavel Machek --- Changes from V3: merged into single patch (it is now small enough), moved dts pieces around (thanks to Thomas Petazzoni), removed clock support (not neccessary with u-boot, needs to be redone).
