Author: jhibbits Date: Sun Sep 17 19:40:17 2017 New Revision: 323684 URL: https://svnweb.freebsd.org/changeset/base/323684 Log: Print the correct bitmask for the running Book-E CPU All the Book-E world is no longer e500v{1,2}. e500mc the 64-bit derivatives do not use the DOZE/NAP bits with MSR[WE], instead using the `wait' instruction to wait for interrupts, and SoC plane controls (via CCSR) for power management.
