Hi Simon, I'm working on implementing a driver for SD/MMC cards in the framework GenodeOS. I think you could help me with your experience in this type of implementation in the u-boot. The hardware platform on which the driver will work is a ODROID-x2 (exynos4412). I use the DWMMC contoller, but I'm not sure if this is the right controller to handle SD/MMC cards in Exynos4412 SoC. The SDHCI controller is most appropriate?
If you're using exynos4412 board, you can choose sdhci or dwmmc controller for eMMC, not SD/SDIO. And in my experiment, dwmmc controller is more appropriate than sdhci.(ex, performance)
Thank you for your help
I'm not really sure - the compatible string for that node is:
compatible = "samsung,exynos4412-dw-mshc";
which is different from what exynos5 uses.
As i know, Some register are difference..but i know it doesn't implemented for those registers at u-boot side. If it should be implemented for upper mode than DDR50, it needs to check the compatible.

Possibly Lukasz / Przemyslaw know about this.
