Enabling cache(s) in MPC8245

Post by Chris Hallinan » Thu Nov 21, 2002 5:40 pm

Can I assume that the kernel turns on both the d-cache and i-cache in
the processor, or is that the responsibility of the startup-* code?

Startup turns on the i-cache when startup main() calls ppc600_init_caches().
The kernel turns on the d-cache.
