Subject: Don't yet configure smmu(4) on Qualcomm SoCs as used on the Lenovo x13s
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=e62200aeef3d2bf14395810c92a54f494ba6774c;p=openbsd

Don't yet configure smmu(4) on Qualcomm SoCs as used on the Lenovo x13s
as it is still not ready for runtime use and probably needs further quirks.

Discussed with deraadt@
