U-Boot for the Ronetix i.MX8MQ-CM board

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

Get and Build the ARM Trusted firmware
======================================
$ git clone https://github.com/nxp-imx/imx-atf
$ cd imx-atf
$ git checkout imx_4.19.35_1.0.0
$ make PLAT=imx8mq bl31
$ cd ..
$ cp imx-atf/build/imx8mq/release/bl31.bin .

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.bin
$ cp firmware-imx-8.9/firmware/ddr/synopsys/lpddr4*.bin .

Build U-Boot
============
$ /opt/cross/aarch64-ronetix-linux-9.2/bin/aarch64-ronetix-linux-gnu-
$ make imx8mq_cm_defconfig
$ make

Burn the flash.bin to MicroSD card offset 33KB
==============================================
$sudo dd if=flash.bin of=/dev/sd[x] bs=1024 seek=33 conv=sync
$sudo dd if=u-boot.itb of=/dev/sd[x] bs=1024 seek=384 conv=sync

Boot
====
Set Boot switch on base board iMX8M-MB to SD boot:
    SW1[8:1]: OFF OFF OFF ON - OFF ON OFF OFF
    SW4[2:1]: OFF OFF
    J4: 1,2 - open; 3,4 - close; 5,6 - open
