Tom Rini 93145335fb nxp: Make board/freescale/common/Kconfig safe to include once in arch/Kconfig 
The way that we use this file currently means that we have to guard it
in every platform Kconfig.  But it is also required in all NXP
platforms, including non-reference platforms.  Make all options in it
have appropriate dependencies so that we can include it a single time
under arch/Kconfig

U-Boot for the Beacon EmbeddedWorks i.MX8M Nano Devkit

Quick Start
===========
- Build the ARM Trusted firmware binary
- Get ddr firmware
- Build U-Boot
- Boot

Get and Build the ARM Trusted firmware
======================================
Note: $(srctree) is U-Boot source directory

$ git clone https://source.codeaurora.org/external/imx/imx-atf
$ git lf-5.10.72-2.2.0
$ make PLAT=imx8mn bl31 CROSS_COMPILE=aarch64-linux-gnu-
$ cp build/imx8mn/release/bl31.bin $(srctree)

Get the DDR firmware
====================
$ wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/firmware-imx-8.9.bin
$ chmod +x firmware-imx-8.9.bin
$ ./firmware-imx-8.9
$ cp firmware-imx-8.9/firmware/ddr/synopsys/lpddr4*.bin $(srctree)

Build U-Boot
============
$ make imx8mn_beacon_defconfig
$ make CROSS_COMPILE=aarch64-linux-gnu-

Burn U-Boot to microSD Card
===========================
$ sudo dd if=flash.bin of=/dev/sd[x] bs=1024 seek=32
