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.MX8MP EVK board

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

Get and Build the ARM Trusted firmware
======================================
Note: $(srctree) is the U-Boot source directory
Get ATF from: https://source.codeaurora.org/external/imx/imx-atf
branch: imx_5.4.3_2.0.0
$ make PLAT=imx8mp bl31
$ sudo cp build/imx8mp/release/bl31.bin $(srctree)

Get the ddr firmware
====================
$ wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/firmware-imx-8.7.bin
$ chmod +x firmware-imx-8.7.bin
$ ./firmware-imx-8.7
$ sudo cp firmware-imx-8.7/firmware/ddr/synopsys/lpddr4_pmu_train_1d_dmem_201904.bin $(srctree)/lpddr4_pmu_train_1d_dmem.bin
$ sudo cp firmware-imx-8.7/firmware/ddr/synopsys/lpddr4_pmu_train_1d_imem_201904.bin $(srctree)/lpddr4_pmu_train_1d_imem.bin
$ sudo cp firmware-imx-8.7/firmware/ddr/synopsys/lpddr4_pmu_train_2d_dmem_201904.bin $(srctree)/lpddr4_pmu_train_2d_dmem.bin
$ sudo cp firmware-imx-8.7/firmware/ddr/synopsys/lpddr4_pmu_train_2d_imem_201904.bin $(srctree)/lpddr4_pmu_train_2d_imem.bin

Build U-Boot
============
$ export CROSS_COMPILE=aarch64-poky-linux-
$ make imx8mp_evk_defconfig
$ export ATF_LOAD_ADDR=0x960000
$ make flash.bin

Burn the flash.bin to the MicroSD card at offset 32KB
$sudo dd if=flash.bin of=/dev/sd[x] bs=1K seek=32 conv=notrunc; sync

Boot
====
Set Boot switch to SD boot
Use /dev/ttyUSB2 for U-Boot console
