Hello,

This series prepares the Cubietech CubieBoard6, based on Actions Semi S500.

Cf. https://en.opensuse.org/HCL:CubieBoard6

With this Device Tree it starts to boot, but it gets stuck during earlycon:

[    1.113517] Kernel panic - not syncing: Attempted to kill init! exitcode=0x0000000b

The same kernel zImage binary boots fine on Guitar, where I instead get:

[    0.865476] cpuidle: using governor ladder
[    0.866283] hw-breakpoint: found 5 (+1 reserved) breakpoint and 1 watchpoint registers.
[    0.866385] hw-breakpoint: maximum watchpoint size is 4 bytes.

I have tested this both with and without owl_secondary_boot(), i.e. my SMP patch series.

Work branch for testing:
https://github.com/afaerber/linux/commits/bg96-next

Cheers,
Andreas

If I return from arch/arm/kernel/hw_breakpoint.c like Scorpion does,
then we avoid the undefined instruction, but it just hangs:

[    0.899948] cpuidle: using governor ladder
[    0.904215] hw-breakpoint: CubieBoard6 detected. Hardware breakpoints
and watchpoints disabled
[  132.032547] random: crng init done

Any ideas?

Regards,
Andreas
