While trying to update gd32vf103-pac, I got:

[WARN svd2rust::generate::device] No settings file provided for RISC-V target. Using legacy interrupts rendering
[WARN svd2rust::generate::device] Please, consider migrating your PAC to riscv 0.12.0 or later

The first count of confusion is that the message doesn't go away after bumping the riscv dependency.

The second count of confusion is the lack of explanation about what the setting file is. The README here is silent, and there doesn't seem to be a mention in the riscv crate docs. This error message could benefit from printing a link to some documentation.
