This adds initial support for the Toradex Verdin iMX8M Plus Quad 4GB WB
IT V1.0B module. They are 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 Plus USB support.
Functionality wise the following is known to be working:
- eMMC, 8-bit and 4-bit MMC/SD card slots
- Ethernet both on-module eQoS and FEC (requires PHY on carrier board)
- 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.

If it is assumed that an unprogrammed fuse has a value of 0 then for
backward compatibility of the code REFTOP_VBGADJ[2:0] must be set to
6 (b'110). Therefore, the table in the code comment can be considered
correct as well as this patch.

It only falls back to this condition when booting from USB, so it

Similar to what has been done before with c5437e5b for u-boot proper, we
enable the SMP bit for SPL as well. This is necessary when SDP booting
straight into Linux, i.e. falcon boot. When SDP boot mode is active, the
ROM code does not set this bit which makes the caches not work once
activated in Linux.
On an i.MX6ULL (528MHz), this reduces a minimal kernel's boot time into
an initramfs shell from ~6.1s down to ~1.2s.
