That would be 
https://git.codelinaro.org/clo/la/openocd-org/openocd/-/blob/qcom_changes/README_QCOM?ref_type=heads

Which says:

Qualcomm specific tools:
- Login to qpm.qualcomm.com
- QUTS: 1.64.1.39 (version & above)
- Qualcomm Host USB Product Suite - QUD QC only : 1.00.63 (supported 
version)
- EUD QC : 2.1.1 (supported version)

I believe the specific versions of QUD and EUD are only available to 
Qualcomm engineers and not even to OEMs, though I might be mistaken.

Kind regards,
