By querying pacman, I get that package uboot-pinebookpro-bsp 1.5-8 is installed on my new
machine.
There seems to be a 2021.4-1 package available also.
Ok, for nvme and deep sleep; it seems it needs bsp patches for uboot to work.

But on the same site, it say we can put the uboot on the eMMC, should be less risks to
debug than flashing on the SPI.

Well there's work to get graphical uboot here :

Is that what you're looking for ?
