vf2-header rewrote

[jonirrings]

thanks for your great work: adapting oreboot for vf2.
I've done the easy part: spl_tool rewrote in Rust

can I transfer it to you, along with vf2-loader.

Oh hi, I am so sorry, I hadn't noticed this issue... 😅

We have another implementation of writing that header within oreboot, though we couldn't figure out which CRC variant to use, so we have a full implementation. I'll adapt your findings, thanks you a lot!

And it happens that I spent the last days figuring out what else goes into the header for secure boot:
starfive-tech/Tools#8

That is now so much already, it makes sense to create a library crate. Would you like to help with that? :)

I have the structs etc here:
