The one thing that I worry about is if these structs are the same for 32 and 64 bit arm.
I see some enums and bools in there - in general the storage size of those isn't even guaranteed to be consistent between different compiler implementations on the same platform, let alone across multiple platforms (especially WRT things like GCC's -fshort-enums).
In practice, under the standard ABIs for 32-bit and 64-bit Arm[1], I'd expect basic types other than longs and pointers to be pretty much the same; it's the imp-def C stuff I'd be a lot less confident about.
