Adam Ford a5685ea488 imx: imx8mn-beacon: Fix out of spec voltage 
The DDR is configured for LPDDR4 running at 1.6GHz which requires
the voltage on the PMIC to rise a bit before initializing LPDDR4
or it will be running out of spec.

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
