Peng Fan aa5bbfd961 board: imx: address dd usage in README
When using cygwin64 "dd (coreutils) 8.26 Packaged by Cygwin (8.26-2)",
the last not 512bytes aligned data wat cut off and not burned into SD
card.

Saying the flash.bin size is 1085608 bytes, not 512bytes aligned. It only
burned 1085440 bytes, the leaving 168 bytes were not burnned and cause
boot issue.

So update README dd command to add "conv=notrunc"

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 conv=notrunc

Boot
====
Set Boot switch to SD boot
