* The set of entries below represent more extensive information
* about the caches, in the form of two entry per cache type,
* one entry containing the cache size in bytes, and the other
* containing the cache line size in bytes in the bottom 16 bits
* and the cache associativity in the next 16 bits.
*
* The associativity is such that if N is the 16-bit value, the
* cache is N way set associative. A value if 0xffff means fully
* associative, a value of 1 means directly mapped.
*
* For all these fields, a value of 0 means that the information
