[PATCH v3 4/7] board: toradex: Add Verdin iMX8M Mini support

[sbabic at denx.de]

> From: Igor Opaniuk <igor.opaniuk at toradex.com>
> This adds 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.
> Boot:
> U-Boot SPL 2020.01-00187-gd411d164e5 (Jan 26 2020 - 04:47:26 +0100)
