Subject: [PATCH 02/20] perf vendors events arm64: Arm Cortex-A7
Add PMU events for Arm Cortex-A7
Update mapfile.csv
Event data based on:
https://github.com/ARM-software/data/tree/master/pmu/cortex-a7.json
which is based on PMU event descriptions from the Arm Cortex-A7 Technical
Reference Manual.
Mapping data (for mapfile.csv) based on:
https://github.com/ARM-software/data/blob/master/cpus.json
which is based on Main ID Register (MIDR) information found in the Arm
Technical Reference Manuals for individual CPUs.
