[PATCH v4 0/4] arm64: dts: juno: CoreSight support updates

[PATCH v4 0/4] arm64: dts: juno: CoreSight support updates

[Sudeep Holla]

Juno r1/r2 boards have different CoreSight infrastructure outside the
CPU clusters. This patchset adds the additional coreSight components to
separate .dtsi files to support these differences.

v1->v2:
	- moved the addition of the STM component into a separate patch

v2->v3:
	- moved the back the common coreSight components back into
	  juno-base.dtsi

v3->v4:
	- removed dtsi nesting in the existing Juno dts file to avoid
	  further addition of such nesting
	- renamed some of the funnel and etf node names(which were
	  previously named confusing them to the labels

[PATCH v4 1/4] arm64: dts: juno: remove dtsi nesting inside tree structure

[Sudeep Holla]

Currently juno-clock.dtsi and juno-base.dtsi are nested badly inside
the device tree structure. It's generally good practice to ensure that
individual dtsi stand by themselves at the top of the file.

This patch removes the nesting of the above mentioned dtsi files and
makes them independent.

[PATCH v4 2/4] arm64: dts: juno: refactor CoreSight support on Juno r0

[Sudeep Holla]

Currently the Coresight components are supported only on Juno r0
variant. In preparation to add support to Juno r1/r2 variants, this
patch refactors the existing coresight device nodes so that r1/r2
support can be added easily.

It also cleans up some of the device node names which were previously
named so as they were confused as the labels rather than the node names.

[PATCH v4 3/4] arm64: dts: juno: add CoreSight support for Juno r1/r2 variants

[Sudeep Holla]

From: Mike Leach <mike.leach-QSEj5FYQhm4dnm+yROfE0A@public.gmane.org>

The CoreSight support added for Juno is valid for only Juno r0.
The Juno r1 and r2 variants have additional components and alternative
connection routes between trace source and sinks.

This patch builds on top of the existing r0 support and extends it to
Juno r1/r2 variants.

Mike,

Can you confirm ? I know TRM had some issues with size of other

Checked both Juno and STM arch manuals - these are in agreement that the STM memory stimulus area is 16MB in size.
Thus for Juno specifically with all masters seeing the same area @ base 0x28000000, <0 0x28000000 0 0x1000000 >  would be the correct description.

Checked both Juno and STM arch manuals - these are in agreement that the STM memory stimulus area is 16MB in size.
Thus for Juno specifically with all masters seeing the same area @ base 0x28000000, <0 0x28000000 0 0x1000000 >  would be the correct description.
