2 * Contains register definitions common to the Book E PowerPC
3 * specification. Notice that while the IBM-40x series of CPUs
4 * are not true Book E PowerPCs, they borrowed a number of features
5 * before Book E was finalized, and are included here as well. Unfortunatly,
6 * they sometimes used different locations than true Book E CPUs did.
