I searched for "FPU" on all svd. These are the inconsistencies I've found.
Let me know if you confirm these inconsistencies or not.

Since this is a long issue, we could do different pull requests to solve it. I would check the related entries once they are solved.

Note

The problem "peripheral FPU has duplicated interrupt" has been solved in
stm32f3x4.yaml with the following code:

FPU:
  _delete:
    _interrupts:
      - FPU
  _add:
    _interrupts:
      FPU:
        description: Floating point unit
        value: 81
