sys/arch/m88k/m88k: m8820x_machdep.c
Log message:
Add a luna88k-specific function to initialize the instruction cmmu
SAPR register.
On luna88k, secondary processors are not disabled while the kernel is
initializing. They are running an infinite loop in
locore.S:secondary_init on non-MULTIPROCESSOR kernel. Then, after
initializing the CMMUs tied to the currently-running processor, we
turn on the instruction cache of other processors to make them
happier.
As a bonus, on non-MULTIPROCESSOR kernel, the power switch LED of
luna88k is blinking green and orange again. According to the hardware
manual, it indicates processors' cache hit status.
