[PATCH] ARM: socfpga: dts: Enable MMC support at correct place in the DT

Marek Vasut marex at denx.de
Thu Dec 17 15:39:04 PST 2015


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.

NOTE: This should not cause any trouble, since I checked all the boards
      for the presence of the HPS SD card slot / eMMC.
