IIRC, it should be possible to verify the TPM device is present before trying to wait for it.
We could skip probing entirely if there's no TCPA or TPM2 ACPI tables. There'd need to be some option to force probing in the case of missing/broken ACPI configurations.
I've just tried the 0001-tpm-Check-for-TPM-related-ACPI-tables-before-attempt.patch (https://mail.coreboot.org/pipermail/seabios/2018-March/012188.html) and it solves my issue with the TPM.
I have tried it with the attached patch of that mail. We have to apply it, also for QEMU. It is this patch here:
Okay, thanks. I applied Steve's patch.
