Shaokun Zhang 9a83c84c3a drivers: base: cacheinfo: Add variable to record max cache line size
Add coherency_max_size variable to record the maximum cache line size
for different cache levels. If it is available, we will synchronize
it as cache line size, otherwise we will use CTR_EL0.CWG reporting
in cache_line_size() for arm64.
