From mboxrd@z Thu Jan 1 00:00:00 1970 From: Magnus Damm Date: Fri, 08 Aug 2014 11:04:37 +0000 Subject: [PATCH] ARM: shmobile: r8a7740: Multiplatform support Message-Id: <20140808110437.2822.33109.sendpatchset@w520> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: linux-sh@vger.kernel.org From: Magnus Damm Enable r8a7740 Multiplatform support for the generic r8a7740 machine vector. No board support is enabled, and the board code for Armadillo 800 EVA DT Reference is left by itself. Once the r8a7740 CCF DTS bits are merged together with SCIF and CMT clock changes and a CMT DT update it will be possible to boot an Armadillo 800 EVA board using the generic r8a7740 machine vector.
