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.
