Hi Okash,
The Cortex-X1 was never a generic licensed CPU with a common MIDR IIUC and was licenced under terms that each partner licensing it had their own MIDR as part of the licensing program (ADP/ELP) and at the time X1 was released TF-A was not supporting such CPU’s in the upstream.
However, with https://git.trustedfirmware.org/TF-A/trusted-firmware-a.git/tree/include/lib... we have started supporting in the upstream an ELP licensed CPU’s with their own MIDR such as https://git.trustedfirmware.org/TF-A/trusted-firmware-a.git/tree/include/lib...
So I guess if Google have a ADP/ELP licence and want to upstream support with their MIDR?
Using the above headerfiles as a guidance in a suitably named header file containing suitable contents something might be upstreamable?

Are there any immediate plans to add support for Cortex-X1 in TF-A? If not then I'll be happy to submit CL for it. For start, it will cover a subset of errata workarounds. Then people can add more as needed. Let me know what you think.
