36 * The top two bits in the first element of the cr_rights[] array contain
37 * total number of elements in the array - 2. This means if those two bits are
38 * equal to 0, we have 2 array elements.
39 * The top two bits in all remaining array elements should be 0.
40 * The next five bits contain array index. Only one bit is used and bit position
41 * in this five-bits range defines array index. This means there can be at most
42 * five array elements.
