Add toradex,verdin-imx8mp for the Verdin iMX8M Plus modules, its nonwifi
and wifi variants and the carrier boards (both Dahlia and the Verdin
Development Board) they may be mated in.

This patch adds the device tree to support Toradex Verdin iMX8M Plus [1]
a computer on module which can be used on different carrier boards.
The module consists of an NXP i.MX 8M Plus family SoC (either i.MX 8M
Plus Quad or 8M Plus QuadLite), a PCA9450C PMIC, a Gigabit Ethernet PHY,
1, 2, 4 or 8 GB of LPDDR4 RAM, an eMMC, a TLA2024 ADC, an I2C EEPROM, an
RX8130 RTC, an optional I2C temperature sensor plus an optional
Bluetooth/Wi-Fi module.
Anything that is not self-contained on the module is disabled by
default.
The device tree for the Dahlia includes the module's device tree and
enables the supported peripherals of the carrier board.
The device tree for the Verdin Development Board includes the module's
device tree as well as the Dahlia one as it is a superset and supports
almost all peripherals available.
So far there is no display functionality supported at all but basic
console UART, USB host, eMMC and Ethernet functionality work fine.

Is this comment needed ? Is it a placeholder for future PCIe support ?

Same here. By the way, you may want to standardize on Verdin or VERDIN
and not mix both. These comments apply to the other files too.

On Dahlia the ethernet connector is routed to the eqos if I'm not
mistaken. On my board U-Boot considers this to be the second ethernet
controller, with the fec being the first one. The mismatch results in
the MAC addresses being swapped between eth0 and eth1 when comparing
U-Boot and Linux. Am I using a too old boot loader, or should the two
ethernet controlls be swapped here ?

Yes, let me also add a TODO in front here. Plus yeah, this capitalized variant just slipped our eyes and I will
change them all to regular Verdin. Thanks for spotting this.

Yes, actually the on-module PHY which is what is routed to the RJ-45 on Dahlia uses the EQOS MAC, correct.

Yes, however, U-Boot does use the EQOS one as primary MAC as well. This is just how U-Boot does things. There
is no easy way to change the actual instance numbering. Actually just like on Linux really with the one
difference that U-Boot will always show both independent whether or not your carrier board even has the second
PHY or not. This is due to U-Boot doing lazy loading aka not touch any Ethernet hardware unless you actually
run some network commands.

No, this alias should really be what ensures the correct MAC addresses.

> ethernet controlls be swapped here ?
Yes, I guess you might not be using latest mainline U-Boot. I just verified this on my table again having both
the Dahlia and Verdin Development carrier boards available. Please note that on the Verdin Development Board
the primary Ethernet is also called eth1. Unfortunately, changing this naming is also not entirely trivial. But
it really should have the proper MAC address.

I've updated U-Boot to 2022-rc4 and I confirm it now works fine.
