Fabio Estevam 9482a60de9 doc: imx8mm_evk: Remove ATF_LOAD_ADDR export
imx8mm-u-boot.dtsi passes the ATF load address via the
'entry' and 'load' properties.

Remove the step that performs the ATF_LOAD_ADDR export, which is
now unneeded.

==========
U-Boot for the NXP i.MX8MM EVK board
Quick Start
-----------
- Build the ARM Trusted firmware binary
- Get ddr firmware
- Build U-Boot
- Boot
Get and Build the ARM Trusted firmware
--------------------------------------
Note: builddir is U-Boot build directory (source directory for in-tree builds)
Get ATF from: https://source.codeaurora.org/external/imx/imx-atf
branch: imx_5.4.47_2.2.0
.. code-block:: bash
$ make PLAT=imx8mm bl31
$ cp build/imx8mm/release/bl31.bin $(builddir)
Get the ddr firmware
--------------------
.. code-block:: bash
$ 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
$ cp firmware-imx-8.9/firmware/ddr/synopsys/lpddr4*.bin $(builddir)
Build U-Boot
------------
.. code-block:: bash
$ export CROSS_COMPILE=aarch64-poky-linux-
$ make imx8mm_evk_defconfig
$ make
Burn the flash.bin to MicroSD card offset 33KB:
.. code-block:: bash
$sudo dd if=flash.bin of=/dev/sd[x] bs=1024 seek=33 conv=notrunc
