Not if it is a _Bool (via stdbool.h or some other way).
A _Bool is always either 0 or 1, and scalar value which is converted to
a _Bool is converted to either 0 or 1.

I believe this is not correct when _Bool is used.
In u-boot a bool is indeed a _Bool (or at least I don't see any other
typedef's and I can see various includes on stdbool.h, I therefore
didn't feel the need to check how bool is arrived at in this particular
file).
