Yes, I'm aware (and I'd assume that there is no reason to ever change that)= . Just for the complete picture, there's also some endianness switch in the NV_PMC_BOOT_1 register I think? > All the CPU architectures our drivers support are expected to be little-e= ndian. Technically, all Rust supported architectures are indeed little-endian. However, the only constraint for the Nova project as by now is 64-bit only.
