This SoC features two clusters composed of: - 4x Cortex A53: 32KB I-cache, 2-way set associative, 32KB D-cache, 4-way set associative, unified 1MB L2 cache, 16-way set associative; - 4x Cortex A73: 64KB I-cache and 64KB D-cache, 4-way set associative, unified 1MB L2 cache, 16-way set associative; With that in mind, add the appropriate properties needed to specify the caches information for this SoC, which will now be correctly exported to sysfs.
