From patchwork Fri Jan 4 15:30:38 2013 Content-Type: text/plain; charset="utf-8" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Subject: [RFC,1/3] ARM: gemini: get platform to build again Date: Fri, 04 Jan 2013 15:30:38 -0000 From: Arnd Bergmann X-Patchwork-Id: 1933501 Message-Id: <1357313440-20092-1-git-send-email-arnd@arndb.de> To: Hans Ulli Kroll Cc: Russell King , Arnd Bergmann , Florian Fainelli , linux-arm-kernel@lists.infradead.org There is no defconfig file for gemini, which has lead to a lot of bitrot. This makes the broken board files, the gpio implementation and the reset logic work again, and fixes the build warnings that got introduced with the changes to the readl/writel prototypes.
