Separate out RPLU device ids and add them to both RPL and
newly created RPL-U subplatforms.

v2: (Matt)
    - Sort PCI-IDs numerically
    - Name the sub-platform to accurately depict what it is for
    - Make RPL-U part of RPL subplatform

v3: revert to RPL-U subplatform (Jani)

This comment really adds nothing, it's exactly the same as the macro
name.

Changing the INTEL_RPLP_IDS impacts arch/x86/kernel/early-quirks.c
too. As is, this drops the early quirks from RPL-U.

Your options are 1) modify early-quirks.c too, or 2) include RPL-U ids
in RPL-P:

  #define INTEL_RPLP_IDS(info) \
+	INTEL_RPLU_IDS(info), \
-	INTEL_VGA_DEVICE(0xA721, info), \
 	INTEL_VGA_DEVICE(0xA7A0, info), \
-	INTEL_VGA_DEVICE(0xA7A1, info), \
-	INTEL_VGA_DEVICE(0xA7A8, info), \
-	INTEL_VGA_DEVICE(0xA7A9, info)
+	INTEL_VGA_DEVICE(0xA7A8, info)

With option 2, you also don't need to add INTEL_RPLU_IDS separately to
subplatform_rpl_ids[] or pciidlist[].

I might lean towards option 2, but no strong opinions.


BR,
Jani.

Yes I missed the early quirks part in this revision. Thank you Jani for pointing out.

Thank you Jani for your suggestion. I am also inclined to the solution of adding RPLU IDs to RPLP platform.

To summarize, we would add the INTEL_RPLU_IDS(info) into INTEL_RPLP_IDS(info).  As Jani pointed out, with this, there is no need to add INTEL_RPLU_IDS separately to
subplatform_rpl_ids[] or pciidlist[]. This also aligns with Bspec(55376) as RPL-U ids are listed under "RPL-P SKUs and Device IDs Info" 

@Matt: I remember, we had discussed a similar option in our communications. Do you have any strong opinion against it?

If not I would go ahead with this implementation.

Regards

Chaitanya
