Priit Laes f94ce9eb05 imx: imx8: Update README with somewhat correct firmware versions
Current setup instructions for i.MX8QM MEK board include somewhat
conflicting instructions, so here's an attempt to fix it.

After trying both sets of firmwares, I can conclude that both of
them fail to work:

- no boot at all with imx-sc-firmware-0.7 / firmware-imx-7.6

- partial success with imx-sc-firmware-1.1 / firmware-imx-8.0:

U-Boot for the NXP i.MX8QM EVK board
Quick Start
===========
- Build the ARM Trusted firmware binary
- Get scfw_tcm.bin and ahab-container.img
- Build U-Boot
- Flash the binary into the SD card
- Boot
Get and Build the ARM Trusted firmware
======================================
$ git clone https://source.codeaurora.org/external/imx/imx-atf
$ cd imx-atf/
$ git checkout origin/imx_4.14.78_1.0.0_ga -b imx_4.14.78_1.0.0_ga
$ make PLAT=imx8qm bl31
And copy the resulting bl31.bin to u-boot directory:
$ cp build/imx8qm/release/bl31.bin path/to/u-boot/
Get scfw_tcm.bin and ahab-container.img
=======================================
$ wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/imx-sc-firmware-1.1.bin
$ chmod +x imx-sc-firmware-1.1.bin
$ ./imx-sc-firmware-1.1.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
And copy the following firmwares to U-Boot folder:
* `imx-sc-firmware-1.1/mx8qm-mek-scfw-tcm.bin`
* `firmware-imx-8.0/firmware/seco/mx8qm-ahab-container.img`
Build U-Boot
============
$ make imx8qm_mek_defconfig
$ make flash.bin
Flash the binary into the SD card
=================================
Burn the flash.bin binary to SD card offset 32KB:
$ sudo dd if=flash.bin of=/dev/sd[x] bs=1024 seek=32
Boot

Set Boot switch SW2: 001100.
