Run the newest u-boot + spl from xfel

[cocus]

Hi, I'm following the tutorial on https://linux-sunxi.org/Allwinner_Nezha#Manual_build, where it states that the newest u-boot sources (not yet merged to mainline) don't require boot0 + TOC1. It produces a single binary file, u-boot-sunxi-with-spl.bin with everything integrated.
I built this, and I'm trying to load it to my DongshanPi Nezha STU.
I've tried to load the binary on different memory addresses, even tried to load the spl + opensbi on different memory addresses (guessing the addresses from the original bootlog) but no luck.

This is the stock log:

does this boot log say something important? can we guess any addresses? I thought opensbi would load at 0x41fc0000, per other examples where they load the opensbi at an address, but the "Firmware Base" ended up +0x400 from this address.

What are the xfel commands I should run to load spl/opensbi/uboot with it?

The version that xfel reports about this chip is:

$ xfel version
AWUSBFEX ID=0x00185900(D1/F133) dflag=0x44 dlength=0x08 scratchpad=0x00045000
