[PATCH v2 0/8] board: toradex: prepare and add Verdin iMX8M Mini support

[Marcel Ziswiler]

Some preparational steps and then adding initial minimal support for the
Toradex Verdin iMX8M Mini Quad 2GB WB IT V1.0A module. They are now
strapped to boot from eFuses which are factory fused to properly boot
from their on-module eMMC. U-Boot supports booting from the on-module
eMMC only, SDP support is disabled for now due to missing i.MX 8M Mini
USB support.

Functionality wise the following is known to be working:
- eMMC, 8-bit and 4-bit MMC/SD card slots
- Ethernet
- GPIOs
- I2C

Boot sequence is:
SPL ---> ATF (TF-A) ---> U-boot proper

ATF, U-boot proper and u-boot.dtb images are packed into a FIT image,
loaded by SPL.
