Espressobin v5 - mainline u-boot seems to work (?!)

So, I thought this was worth a try:

My own kernels boot but I'm still having issues with the latest armbian SD card images (same issue with 2017 and 2018 u-boots).

I'm not game to touch atf - someone with Marvell's wtp tools set up can do that

Mainline U-Boot should really work fine. Just build ARM trusted firmware and U-Boot according to the latest guide:

https://trustedfirmware-a.readthedocs.io/en/latest/plat/marvell/armada/build.html

(search for example how to build production release of Marvell firmware image)

I believe Armbian already produce mainline U-Boot for this board so you don't need to compile yourself. The package is named `linux-u-boot-espressobin-edge` so you need to extract it yourself. That is what I used to boot vanilla Debian with grub-efi. However, ATF BL1 BL2 BL31 are listed as version 1.5 instead of 2.4. U-Boot was fine and distro boot works so I didn't worry about those.
