The Kryo cores share errata 1009 with Falkor, so add their model
definitions and enable it for them as well.

Can you double-check this, please? My Pixel-1 phone claims something with
0x201, but I don't know if that's what you were aiming for. It would be
great if Qualcomm could document these register fields somewhere, especially
since we're trying to work around their hardware errata for them.

That said...

... why aren't you following what we do for E1003 and using the
'is_kryo_midr' callback to match these CPUs?

These are not Kryo part numbers (8998+).  They are Hydra ones.

I wish I could point you to public documentation.  I don't happen to 
know where it is.  As far as 8996 goes, there are quite a few part 
numbers.  The ones I could find are:
201
205
211
241
251

281 happens to be QDF2432

 From asking around, I found someone in the know.  We don't have public 
documentation, but I can follow up to try to create something - its 
likely going to take a bit.  I was given the following information to 
share.  This is specific to Hydra only-

MIDR[15:12] = PART[11:8]
Hydra and technology node differentiator (0x1 = Hydra 16nm; 0x2 = Hydra 
14nm; 0x3 = Hydra 10nm)

MIDR[11:10] = PART[7:6]
This corresponds to the cluster revision number

MIDR[9:8] = PART[5:4]
Technology variant within the node

MIDR[7:6] = PART[3:2]
0b00 = 512KB L2
0b01 = 1MB L2
0b10 = 2MB L2
0b11 = 4MB L2

MIDR[5:4] = PART[1:0]
0b00 = uni-core
0b01 = dual-core cluster
0b10 = tri-core cluster
0b11 = quad-core cluster

Thanks for digging up the details, Jeffrey. As far as I can tell, our
'is_kryo_midr()' function will return 'true' for all of these, so I think
that's what we should be using for this erratum workaround. Would that work
for you?

I also agree, but believe that it should be renamed to is_hydra_midr() 
as Bjorn suggests, since there is a "kryo" architecture which has 
different part ids, and I think continuing to use "kryo" for the current 
errata will be confusing if there is errata for the kryo architecture in 
the future.

Of course, it doesn't help that marketing seems to have used "kryo" for 
both architectures.
