Common traits for identical IP blocks

I want to be able to write generic functions that can operate on any instance of the same peripheral across a vendor's product line, or any instance of the same peripheral within a given chip.

For a concrete example: as far as I know, ST Micro uses the same bxCAN IP on every chip in the STM32 line that has a CAN peripheral, and on some chips they have multiple copies of the bxCAN peripheral. So I'd like to be able to write generic code that uses a bxCAN peripheral, independent of which STM32 product you're building for and which instance of the peripheral you're using.

I think a lot of the relevant information can be inferred directly from the .svd files, by checking whether two peripherals have identical register definitions, ignoring reset values. But I can't decide how much manual intervention makes sense.

What are your thoughts?

The issue names no source files or tests. Start by examining how .svd files describe peripheral register definitions and how svd2rust represents them, then determine whether identical blocks can be identified reliably while ignoring reset values. Done would require an agreed design for generic access across repeated peripherals and a defined validation plan.
