Hello Jonas,

> different BMIPS flavours on them, regardless of SMP support enabled in
> the kernel.
>
> The first few patches clean up BMIPS itself and prepare it for multi-cpu

> CPU.

After fixing the typo on BMIPS4350 vs BMIPS4380 and fixing the
following (which I will submit just in a few minutes)
@@ -187,7 +187,7 @@ static void bmips_boot_secondary(int cpu, struct task_struct
} else {
if (cpu_is_bmips4350() || cpu_is_bmips4380()) {
/* Reset slave TP1 if booting from TP0 */
- if (cpu_logical_map(cpu) == 0)
+ if (cpu_logical_map(cpu) == 1)
set_c0_brcm_cmt_ctrl(0x01);
} else if (cpu_is_bmips5000()) {
if (cpu & 0x01)
it works just nicely on BMIPS4380. I plan on doing some testing on
BMIPS5000 later this week.
Thanks!
