This commit adds initial support for the Toradex Apalis iMX8QM 4GB WB IT V1.0B module. Unlike the V1.0A early access samples exclusively booting from SD card, they are now strapped to boot from eFuses which are factory fused to properly boot from their on-module eMMC. U-Boot supports either booting from the on-module eMMC or may be used for recovery purpose using the universal update utility (uuu) aka mfgtools 3.0. Functionality wise the following is known to be working: - eMMC, 8-bit and 4-bit MMC/SD card slots - Gigabit Ethernet - GPIOs - I2C Unfortunately, there is no USB functionality for the i.MX 8QM as of yet.

U-Boot for the Toradex Apalis iMX8QM V1.0B Module
Quick Start
===========
- Build the ARM trusted firmware binary
- Get scfw_tcm.bin and ahab-container.img
- Build U-Boot
- Load U-Boot binary using uuu
- Flash U-Boot binary into the eMMC
- Boot
Get and Build the ARM Trusted Firmware
======================================
$ git clone -b imx_4.14.78_1.0.0_ga https://source.codeaurora.org/external/imx/imx-atf
$ cd imx-atf/
$ make PLAT=imx8qm bl31
Get scfw_tcm.bin and ahab-container.img
=======================================
$ wget https://github.com/toradex/meta-fsl-bsp-release/blob/toradex-sumo-4.14.78-1.0.0_ga-bringup/imx/meta-bsp/recipes-bsp/imx-sc-firmware/files/mx8qm-apalis-scfw-tcm.bin?raw=true
$ mv mx8qm-apalis-scfw-tcm.bin\?raw\=true mx8qm-apalis-scfw-tcm.bin
$ wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/firmware-imx-8.0.bin
$ chmod +x firmware-imx-8.0.bin
$ ./firmware-imx-8.0.bin
Copy the following binaries to the U-Boot folder:
$ cp imx-atf/build/imx8qm/release/bl31.bin .
$ cp u-boot/u-boot.bin .
Copy the following firmware to the U-Boot folder:
$ cp firmware-imx-8.0/firmware/seco/ahab-container.img .
Build U-Boot
============
$ make apalis-imx8qm_defconfig
$ make u-boot-dtb.imx
Load the U-Boot Binary Using UUU
================================
Get the latest version of the universal update utility (uuu) aka mfgtools 3.0:
https://community.nxp.com/external-link.jspa?url=https%3A%2F%2Fgithub.com%2FNXPmicro%2Fmfgtools%2Freleases
Put the module into USB recovery aka serial downloader mode, connect USB device
to your host and execute uuu:
sudo ./uuu u-boot/u-boot-dtb.imx
Flash the U-Boot Binary into the eMMC
=====================================
Burn the u-boot-dtb.imx binary to the primary eMMC hardware boot area partition:
load mmc 1:1 $loadaddr u-boot-dtb.imx
setexpr blkcnt ${filesize} + 0x1ff && setexpr blkcnt ${blkcnt} / 0x200
mmc dev 0 1
mmc write ${loadaddr} 0x0 ${blkcnt}
Boot
