hi Tiger,
Sorry! It's a little late.
Albert has merged arm64 patch set. I have tested and it works fine on

Armv7 and Armv8 allow outer cache exist, it is outside of the architecture
defined cache hierarchy and can not be manipulated by architecture defined
instructions. It's processor specific.
This patch merge v7_outer_cache_* and v8 l3_cache_*.

The cache disable operation shoud be performed after flush_dcache_all().
If cache disable operation is performed before
flush_dcache_all(), flush_dcache_all() store data directly to memory
and may be overrided by data copy in cache.

When test failed, the mtest command will output error information
