U-Boot for the NXP i.MX8MN EVK board

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

Get and Build the ARM Trusted firmware
======================================
Note: srctree is U-Boot source directory
Get ATF from: https://source.codeaurora.org/external/imx/imx-atf
branch: imx_4.19.35_1.1.0
$ make PLAT=imx8mn bl31
$ cp build/imx8mn/release/bl31.bin $(srctree)

Get the ddr firmware
=============================
$ wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/firmware-imx-8.5.bin
$ chmod +x firmware-imx-8.5.bin
$ ./firmware-imx-8.5
$ cp firmware-imx-8.5/firmware/ddr/synopsys/ddr4*.bin $(srctree)

Build U-Boot
============
$ export CROSS_COMPILE=aarch64-poky-linux-
$ make imx8mn_ddr4_evk_defconfig
$ export ATF_LOAD_ADDR=0x960000
$ make flash.bin

Burn the flash.bin to MicroSD card offset 32KB
$sudo dd if=flash.bin of=/dev/sd[x] bs=1024 seek=32

Boot
====
Set Boot switch to SD boot
