I think that series was dropped because it was too soc-specific and overlaps with the v8.2
kernel first support. That series was superseded by:
lore.kernel.org/r/1562086280-5351-1-git-send-email-baicar@os.amperecomputing.com

Can you work with Tyler on a combined series? The combined support may need to look quite
different. (DT and big/little being the obvious differences).

I'm afraid this is the tip of the kernel-first-RAS iceberg.


Thanks,

James
