16 * one entry containing the cache size in bytes, and the other
17 * containing the cache line size in bytes in the bottom 16 bits
18 * and the cache associativity in the next 16 bits.
19 *
20 * The associativity is such that if N is the 16-bit value, the
21 * cache is N way set associative. A value if 0xffff means fully
22 * associative, a value of 1 means directly mapped.
23 *
24 * For all these fields, a value of 0 means that the information
