Can you try the patch below and let me know?
I tried this patch and now Ux500 WORKS. So this patch is definitely
something you should apply.
- if (is_frankengic())
+ this_cpu_write(sgi_intid, intid);
This needs changing to irqstat to compile as pointed out by Jon.
Tested-by: Linus Walleij <linus.walleij@xxxxxxxxxx>
Thanks a lot for that.
Still need to understand why some of Jon's systems are left unbootable,
despite having similar GIC implementations (Tegra194 and Tegra210 use
the same GIC-400, and yet only one of the two boots correctly...).
So far, I have only tested this patch on Tegra20. Let me try the other
failing boards this morning and see if those still fail.
