u-boot is able to find the USB stick with the Buster RC1 installer and
boot it. I made many cycles, this happens reliably.
The first road block is the partitioner, if let alone it creates a
regular GPT (don't know if it could be instructed to create a legacy MBR
instead) and so overwrites the spl+u-boot leaving the board completely
unbootable.
To work around this, I prepare the GPT manually with the famous 4 entries
(see the extra menu in fdisk) and configure the partitions at my wish,
then the installer can reuse them preserving my hand crafted GPT and
the bootability up to u-boot.
The installation process goes nicely but grub installation fails,
as it seems to be expected [0]. The board is left unbootable.
This is where I am, so booting kernel+initrd+dtb: yes (the installer
from USB), no (the just installed system).
To be fair, I should check that the installer can be executed via tftp
and via partition on the sdcard before claiming it's all fine with
u-boot on this board.
Need to further investigate why u-boot cannot continue the boot. I
don't know how a properly working arm64 world looks like and what's
missing from my installation, if it's not just grub.
I am not able to quickly hack a boot, the kernel is not just a familiar
zImage and bootz is not even available. It must have something to do
with all this UEFI order of things for which I need grub (or not?) ;)

I think I addressed all your comments, MR #5 is updated for sid while
#6 is ready for master.
