Nicely done (and nicely formatted for review too), thanks.
I have some suggestions:
(1) in the commit message, it might be worth mentioning (additionally)
that we undo commit d272449d9e1e ("OvmfPkg: raise DXEFV size to 11 MB",
2018-05-29).
(2) Please don't forget to rename & replace XenOvmf -> OvmfXen (in file
names, the commit message, and the patch body).

(3) Here you diverge from the general pattern of:
- SMM_REQUIRE==TRUE --> drop the full block
- SMM_REQUIRE==FALSE --> drop the condition, keep the block
For consistency with the pattern, you sould *in theory* only drop the
condition.
Let's see what this change effects.
You remove the driver from the APRIORI DXE file. That means the DXE Core
will be at liberty to launch the driver at any time, provided DEPEXes
are satisfied.
This wouldn't be correct for the original FDF file, because there we
need an arbitration between this driver and the emulation driver,
dependent on flash detection. Therefore the original platform first
launches the flash driver, and falls back to the emu driver if flash is
not present. Except in case of SMM_REQUIRE, in which case *both* of
those drivers are replaced by the SMM flash driver (and no arbitration
occurs, because flash is a hard requirement).
On Xen, SMM_REQUIRE is indeed assumed FALSE, but we also don't really
need the arbitration, because we know the flash detection will always
fail. Therefore, it is correct to remove the flash driver from the
APRIORI DXE file -- but then, shouldn't we remove the driver itself from
the DSC and FDF files too?
I mean, if it doesn't matter *when* it is launched, then you don't need
to launch it *at all*, I believe.
If you agree, then it's OK (but not required) to split this change to a
separate patch -- as I said it diverges from the general pattern and may
deserve a bit more explanation.
(4) You might want to remove/revert SEV-related modules as well (I'm
unsure if AMD SEV works on Xen -- if it does, then please ignore):
- IoLib|MdePkg/Library/BaseIoLibIntrinsic/BaseIoLibIntrinsicSev.inf
(refer to "git blame" to see what to revert it to)
-
MemEncryptSevLib|OvmfPkg/Library/BaseMemEncryptSevLib/BaseMemEncryptSevLib.inf
- NULL|OvmfPkg/Library/PlatformHasIoMmuLib/PlatformHasIoMmuLib.inf
- OvmfPkg/AmdSevDxe/AmdSevDxe.inf
- OvmfPkg/IoMmuDxe/IoMmuDxe.inf
This can be a separate patch again.
(5) I think you could change the QemuFwCfgS3Lib resolution to
"BaseQemuFwCfgS3LibNull.inf", and then remove all the S3 modules --
search OvmfPkg, and generally the edk2 tree, for " PcdAcpiS3Enable".
See also module names having "S3" in the name, in the FDF/DSC files.
This would probably be a separate patch.
Thanks,
Laszlo
