From 2531f067ea0e9c77b081445800de8e9584d7d4ab Mon Sep 17 00:00:00 2001 From: Andrew Turner Date: Tue, 27 Jul 2021 19:28:33 +0000 Subject: [PATCH] Teach the arm64 kernel to identify the Arm AEM The Arm Architecture Envelope Model is a simulator that models the architecture rather than any specific implementation. Add its part ID macro and add it to the list of Arm CPUs we can decode.
