OK, I think this wants to be called use_boot42_instead(), approximately.
...and I've fortified the code accordingly:
impl NV_PMC_BOOT_0 {
pub(crate) fn use_boot42_instead(self) -> bool {
// "Future" GPUs (some time after Rubin) will set `architecture_0`
// to 0, and `architecture_1` to 1, and put the architecture details in
// boot42 instead.
self.architecture_0() == 0 && self.architecture_1() == 1
}
