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.
