I tested it using:
LOG_USER("arm920_virt2phys virt=0x%08x -> phys = 0x%08x", virt, *phys);
just before the return statement.
It printed physical == virtural, so in my case at least, it is working ;)
I mean the vir2phys function is working, the cache flush still crashes my app.
About the data cache flush, I'm pretty sure this instruction is not in the data
cache. What happens when we flush an address that is not in the data cache?
