Okay, thanks Lorenzo. I will ping Bjorn for patch 1.

And yes, the amount of HW quirks is overwhelming. We do have a process
internally to track each quirk and a plan to address them in the next
revision of the silicon based on priority, but that's largely managed by
our ASIC team. Bottom line is the next revision of the ASIC should
require much less of these quirks though.

Thanks,

Ray
