+Subject: [PATCH 3/5] ARM: socfpga: dts: Enable MMC support at correct place in
+ the DT
+
+The socfpga.dtsi explicitly enabled MMC support, but not all boards are
+equiped with an MMC card. There are setups which only have QSPI NOR.
+Therefore, disable the MMC support on socfpga.dtsi level and enable it
+on per-board basis.
