SoCs containing 0x14CA are present both in datacenter parts that
support SEV as well as client parts that support TEE.

Herbert,

I noticed you sent out the 6.1 PR already.  So I Just wanted to make sure this
didn't get overlooked as it's already got a T-b/A-b.

Thanks!

Hi Mario:

This didn't make the deadline for inclusion in my 6.1 PR.  Is there
any reason why it has to go in this merge window rather than the next?

Thanks,

Some other maintainers take new IDs as fixes.  Particularly when they're 
good candidates for cc stable.

The main reason I wanted to see it sooner is so that it has more time to 
percolate to the various downstream distros so that errors stemming from 
the lack of this ID declaration aren't prevalent when using this SOC.

Sorry but this is not persuasive enough for me.  If you want a patch
to make a particular merge window, make sure that you get it in early
enough.
