This series enables future IP trace features Embedded Trace Extension
(ETE) and Trace Buffer Extension (TRBE). This series applies on
v5.12-rc4 + some patches queued. A standalone tree is also available here [0].
The queued patches (almost there) are included in this posting for
the sake of constructing a tree from the posting.

ETE is the PE (CPU) trace unit for CPUs, implementing future
architecture extensions. ETE overlaps with the ETMv4 architecture, with
additions to support the newer architecture features and some restrictions
on the supported features w.r.t ETMv4. The ETE support is added by extending
the ETMv4 driver to recognise the ETE and handle the features as exposed by
the TRCIDRx registers. ETE only supports system instructions access from the
host CPU. The ETE could be integrated with a TRBE (see below), or with
the legacy CoreSight trace bus (e.g, ETRs). Thus the ETE follows same
firmware description as the ETMs and requires a node per instance.

Applied to fixes, thanks!
