From 03439e4064a9aff6185d081540a97e7afc32ac31 Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Mon, 3 Aug 2015 18:31:51 +0200 Subject: [PATCH] arm: socfpga: Add temporary workaround for missing SD/MMC patches Add a small workaround into the platform code which forces the SDMMC into 8-bit mode (the default configuration for all socfpga platforms) to work around breakage caused by missing patches in mainline which switch the probing of SD/MMC to OF instead of static configuraiton. The patches will hit mainline after the SPL series, so to avoid build issues, add this small temporary workaround.
