[PATCH 1/3] dt-bindings: mips: cpu: Add property for broken HCI information

From: Gregory CLEMENT
Date: Thu Oct 17 2024 - 10:47:25 EST


Some CM3.5 reports show that Hardware Cache Initialization is
complete, but in reality it's not the case. They also incorrectly
indicate that Hardware Cache Initialization is supported. This
optional property allows warning about this broken feature that cannot
be detected at runtime.
