commit 3e666ad0
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I5YCYK
CVE: NA

Reference: https://lore.kernel.org/r/20210405164307.1720226-13-suzuki.poulose@arm.com

--------------------------------------------------------------------------

Add support for handling the system registers for Embedded Trace
Extensions (ETE). ETE shares most of the registers with ETMv4 except
for some and also adds some new registers. Re-arrange the ETMv4x list
to share the common definitions and add the ETE sysreg support.
