What is the inconsistency you're observing and what analysis methods do
you use - can you go in more detail?

Unfortunately, I'm not very used to libc file handling. However, from
what I know, this looks good. You could check whether it's correct by
executing it in a Linux (using a properly prepared RAM region).
Regarding your cache-flush SMC: Have you added a certain register value,
say r0=1234 that identifies the cache-flush SMC at the tz_vmm side? Are
you sure to do a flush of all entries of all non-secure ARM data-cache
levels?
Cheers,
Martin
