in this particular case, it seems that the u8 typedef is done at the architecture level, and efi.h doesn't include asm/types.h that define it. Maybe it's as simple as that. Otherwise, it includes linux/types.h that defines uint8_t, we can use that instead.

Digging into this again, it seems clear that this doesn't work since 'u8' is meant for kernel space while user space should use '__u8'. Envcrc *is* userspace, so using uint8_t everywhere makes more sense.

Yes, but the offending variable is in include/efi.h, which would be included by both (but probably not intentionally in the envcrc case).
