From cf1dad9d7f14ddf555baa0fcc82d17d5f29d3ae2 Mon Sep 17 00:00:00 2001 From: Tushar Behera Date: Wed, 31 Aug 2011 16:57:37 +0900 Subject: [PATCH] ARM: EXYNOS4: Add support for secondary MMC port on ORIGEN Secondary MMC port on ORIGEN is connected to sdhci instance 0. Support for secondary MMC port is extended by registering sdhci instance 0. Since sdhci instance 2 can contain a bootable media, sdhci instance 0 is registered after instance 2.
