The cm-fx6 module has an on-board spi flash chip. Enable mtd support and the mtdparts command. Also define a default partitioning, add it to the default environment, and enable support to overwrite the partitioning defined in a device tree by it. Finally, probe for the chip on preboot to register the flash chip and, thus, establish the connection between the mtd environment settings and the actual device. These changes move the effective default partitioning from the device tree shipped with the vendor kernels to U-Boot which becomes the single point of definition for the partitioning for all device tree based kernels (in particular, for the upstream Linux kernel which does not have a default partitioning defined in its device tree).
