Nice background on OpenSBI.

Seems AMD with #openSIL could end up more open than RISC-V with their affinity to vintage hardware architecture #OpenSBI.

I found the fix to the #DRAM issue on the #JH7100 / #VisionFive1 - missed copying one stupid function call, whoopsies!

`disable_u74_memaxi_remap(1)` - that was it.

So, in other words: @oreboot now loads the #OpenSBI + U-Boot blob successfully and runs it from the cacheable RAM.

Next week I'll recap that and then get back to drafting #RustSBI, but the rest will be for next year.

I've mostly used the #pinephone with #mobian for communications.

The other day I got an email while sitting on the couch that a alternate #reproduciblebuilds patch for #opensbi was merged.

The smart thing to do would be to ssh into another machine to confirm the fix.

The *fun* thing to do was to confirm the fix by building the package twice on the pinephone using a standard #debian tool, sbuild.

It is so nice to have a handheld computer instead of a phone!
