ARM: S5PV210: Add SDHCI devices for GONI board
This patch add support for SDHCI blocks on Samsung Goni board. The following host controllers are defined: 1. Internal MoviNAND device (permanently wired to the controller) 2. Internal WiFI SDIO device (card is activated by power regualor) 3. External MMC/SD socket (card detection is provided by external gpio interrupt) Signed-off-by: Marek Szyprowski <m.szyprowski@samsung.com> Signed-off-by: Kyungmin Park <kyungmin.park@samsung.com> Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>
