That's fine, since there is no real difference in the flashing procedure
between boot2 and normal firmware AFAICT, the tool should work with that
firmware just fine.

And a slight correction, but "better for the ARM processor" is wrong,
because it's _always_ been the ARM updating the normal (ie non-boot2)
firmware in this scenario, even if the userspace tool was doing it.
