[PATCH V2 1/7] arm: dts: imx8mn-u-boot: Create common imx8mn-u-boot.dtsi

[sbabic@denx.de]

> Multiple boards create duplicate entries in their respective
> -u-boot.dtsi files which all basically do the same thing.
> To consolidate these and make it easier to make improvements
> going forward, consolidate them all into one place.
> This file creates a flash.bin image using binman, and supports
> LPDDR4, DDR4 and DDR3.  Since individual boards use different
> peripherals and different UART ports, those entries were kept
> in their respective board files, but the spba1 node was addded
> which contains all UART1-3 to help facilitate SPL_DM_SERIAL.
> Individual users will still need to include their respective
> UART and pinctrl nodes for those UARTS.
> This consolidated file also supports generating a flash.bin file
> which can boot from flexSPI if CONFIG_FSPI_CONF_HEADER is
> enabled.

Applied to u-boot-imx, master, thanks !
