Subject: [PATCH v2 0/6] coresight: syscfg: Extend configfs for config load
Date: Tue, 30 Nov 2021 22:00:54 +0000	[thread overview]
Message-ID: <20211130220100.25888-1-mike.leach@linaro.org> (raw)

This set extends the configfs support to allow loading and unloading of
configurations as binary files via configfs.

Additional attributes - load, unload and last_load_status are provided to
implement the load functionality.

Routines to generate binary configuration files are supplied in
./samples/coresight.

Example generator and reader applications are provided.

Additional Makefile.host supplied to build the generator and reader
applications on the host system separate from a cross compiled kernel.

Documentation is updated to describe feature usage.

Applies and tested on latest coresight/next that includes the
previous coresight configuration dynamic load patchset.

Changes since v1:
1) Rebased to coresight/next - 5.16-rc1 with previous coresight config
set applied.
2) Makefile.host fixed to default to all target.
