Hello! It is nice to see support for another A385 board!
I have few comments, see below...

If you have only #include "mvebu-u-boot.dtsi" line in your -u-boot.dtsi
file then this -u-boot.dtsi file should not be needed at all. Because
U-Boot build process include it automatically when board -u-boot.dtsi
does not exits.

Could you send DTS file also into Linux kernel?

As it is Armada 385 board, you should not have there "marvell,armada388"
and also you should not have there "marvell,a385-db" which refers to the
Marvell Development Board (different one).

These two nodes have &i2c0 and &i2c1 pointers defined in armada-38x.dtsi
so you can move them out of the internal-regs. Like you did for &spi1
and &nand_controller.

Same for &uart0

status = "ok" is ignored. Correct is "okay".

And it has &usb0.

Could you sort device nodes by addresses? It is common to define nodes
in ascending order.
Also it has &pinctrl

IIRC convention for device node name is to use only hyphens and for DTS
pointers only underscore. So it should be something like this:
pmx_power_button: pmx-power-button {
...
};

Personally, I would use labels "u-boot" and "u-boot-env". But I'm not
sure what others think...

I think that checkboard() function is not needed here. It does not check
for anything (always returns 0) and printing board name is done by
common u-boot function show_board_info().

Do you need to define partitions also here? Because on Turris Omnia is
U-Boot parsing partitions from DTS file and CONFIG_MTDPARTS_DEFAULT is
not specified in configs/turris_omnia_defconfig at all.

I see that you have also NAND with UBIFS in DTS file. What is stored on
NAND? Does not it have bootable system and should be in default boot
target list?
