Subject: [Intel-gfx] [PATCH v4 10/14] mei: mkhi: add memory ready command
Date: Wed, 29 Jun 2022 14:29:09 +0300	[thread overview]
Message-ID: <20220629112913.1210933-11-alexander.usyskin@intel.com> (raw)
In-Reply-To: <20220629112913.1210933-1-alexander.usyskin@intel.com>

From: Tomas Winkler <tomas.winkler@intel.com>

Add GSC memory ready command.
The command indicates to the firmware that
extend operation memory was setup and
the firmware may enter PXP mode.
