apicula: add support for magic sip pins #1370

Closed pepijndevos closed 1 month ago

pepijndevos commented 2 months ago

While we have documented the sdram pins of some devices we lack the ability to automatically place them like the vendor tools do. For better compatibility and user friendliness this PR adds the ability to constrain these magic pin locations.

It seems to load the constraints but I have yet to test if sdram actually functions, which isn't super trivial.

Does this still need to be a draft or are we okay merging this?

I still need to test it actually works

pepijndevos commented 1 month ago

Okay so this works on all the devices I've been able to test so I think this is ready
