Subject: [PATCH 0/6] coresight: syscfg: Extend configfs for config load.
Date: Mon, 1 Nov 2021 22:47:25 +0000 [thread overview]
Message-ID: <20211101224731.27870-1-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.
Documentation is updated to describe feature usage.
Set applies on top of dynamic load set here:
