From mboxrd@z Thu Jan 1 00:00:00 1970 From: Bartosz Golaszewski Date: Fri, 04 May 2018 13:27:28 +0000 Subject: [PATCH v3 0/3] sh: make early_platform code SuperH-specific Message-Id: <20180504132731.14574-1-brgl@bgdev.pl> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: linux-arm-kernel@lists.infradead.org I recently started a discussion about the need for a proper early device probing mechanism[1]. One that would be based on real platform drivers and support both platform data and device tree. While we're far from reaching any consensus on the implementation, Arnd suggested that I start off by moving the SuperH-specific early platform drivers implementation to arch/sh[2]. This series is the first attempt at making way for a new, less hacky implementation. The first patch removes the last instance of a non-sh driver using the early_platform API. It can be removed since ARM no longer probes early drivers. The second patch moves all the early_platform code to arch/sh. The last patch prefixes all early_platform symbols with 'sh_'.

This series is the first attempt at making way for a new, less hacky implementation. The first patch removes the last instance of a non-sh driver using the early_platform API. It can be removed since ARM no longer probes early drivers. The second patch moves all the early_platform code to arch/sh. The last patch prefixes all early_platform symbols with 'sh_'.
