Alifer Moraes a604b67b87 arm: dts: imx8mq-evk: add phy-reset-gpios for fec1
Instead of resetting the ethernet phy through functions in imx8mq_evk.c, let the
driver reset the phy via dts description adding a reset duration of 10 ms
following atheros 8031's datasheet recommendation.

U-Boot for the NXP i.MX8MQ EVK board

Quick Start
===========
- Build the ARM Trusted firmware binary
- Get ddr and hdmi fimware
- 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_1.0.0
$ make PLAT=imx8mq bl31
$ cp build/imx8mq/release/bl31.bin $(builddir)

Get the ddr and hdmi firmware
=============================
$ wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/firmware-imx-7.9.bin
$ chmod +x firmware-imx-7.9.bin
$ ./firmware-imx-7.9.bin
$ cp firmware-imx-7.9/firmware/hdmi/cadence/signed_hdmi_imx8m.bin $(builddir)
$ cp firmware-imx-7.9/firmware/ddr/synopsys/lpddr4*.bin $(builddir)

Build U-Boot
============
$ export CROSS_COMPILE=aarch64-poky-linux-
$ make imx8mq_evk_defconfig
$ make flash.bin

Burn the flash.bin to MicroSD card offset 33KB
$sudo dd if=flash.bin of=/dev/sd[x] bs=1024 seek=33

Boot
====
Set Boot switch SW801: 1100 and Bmode: 10 to boot from Micro SD.
