[PATCH 1/2] doc: imx8mp_evk: Remove unneeded export ATF_LOAD_ADDR line
From: Fabio Estevam festevam@denx.de
Originally, exporting the ATF_LOAD_ADDR was required, but since binman has been used to generate the flash.bin, it is no longer needed to do such manual export.
The ATF address is now passed via binman in imx8mp-u-boot.dtsi:
atf { description = "ARM Trusted Firmware"; type = "firmware"; arch = "arm64"; compression = "none"; load = <0x970000>; entry = <0x970000>;
atf_blob: atf-blob { filename = "bl31.bin"; type = "atf-bl31"; }; };
Remove the unneeded export ATF_LOAD_ADDR line.

To make it consistent with the instructions from other NXP imx8m boards, such as imx8mm-evk and imx8mn-evk, use U-Boot in-tree build in the examples.
