+Subject: [PATCH] mmc: xenon_sdhci: Add missing common host capabilities
+
+Use mmc_of_parse() to set the common host properties. That includes
+"bus-width", so parsing it can be removed from the driver.
+
+But more importantly, "non-removable" is now respected, which fixes
+the usage of eMMC.

+Subject: [PATCH] arm: mvebu: Espressobin: Set environment variable fdtfile
+
+Required for the generic distro mechanism.
+
+Linux ships with 4 variants:
+marvell/armada-3720-espressobin-v7-emmc.dtb
+marvell/armada-3720-espressobin-v7.dtb
+marvell/armada-3720-espressobin-emmc.dtb
+marvell/armada-3720-espressobin.dtb
+
+Use available information to determine the appropriate filename.
+
+Tested on a v5 board without eMMC.
