Usually the slave devices are specific to board, so it's better to
defined these in dts file instead of dtsi. And also I'm unable to
differnetiate SOC entries vs Board entries? Please check and if
possible move SOC entries in dtsi, this will be easy for longterm
mainataince.

> +U-Boot for LogicPD i.MX6 Development Kit
> +----------------------------------------
> +
> +This file contains information for the port of U-Boot to the Logic PD Development kit.
> +
> +Logic PD has an i.MX6 System On Module (SOM) and a correspondong development
> +board. SOM has a built-in microSD socket, DDR and NAND flash. The development kit has
> +an SMSC Ethernet PHY, serial debug port and a variety of peripherals.
> +
> +On the intial release, the SOM came with an i.MX6D and i.MX6Q.
> +
> +For more details about Logic PD i.MX6 Development kit, visit:
> +https://www.logicpd.com/
> +
> +Building U-Boot for Logic PD Development Kit
> +--------------------------------------------
> +To build U-Boot for the Dual and Quad variants:
> +
> + make imx6q_logic_defconfig
> + make u-boot.imx ARCH=arm CROSS_COMPILE=arm-linux-
> +
> +
> +Flashing U-Boot into the SD card
> +--------------------------------
> +
> +See README.imximage for details on booting from SD
> +
> +Flashing U-Boot into NAND
> +-------------------------
> +Once in Linux with MTD support for the NAND on /dev/mtd0, program U-Boot with the following:
> +with:
> +
> + kobs-ng init -v -x u-boot.imx
Since this board enabled-of the image should be u-boot-dtb.imx or
similar like dtb enabled image.
