This patch set implements eMMC on Amlogic Meson GX (S905). It's based on Carlo Caione's work submitted here: http://lists.denx.de/pipermail/u-boot/2016-May/254391.html

Changes to the original version: - BLK support added - fully DT-based now - minor general refactoring

The driver was successfully tested on a Odroid C2.

Note: On Odroid C2 eMMC is MMC device 1. So you have to switch from MMC device 0 to 1 first when testing from uboot prompt.
