Subject: [PATCH 15/24] boards: qemu-virt: add security policies
Date: Wed, 20 Aug 2025 15:17:59 +0200 [thread overview]
Message-ID: <20250820-security-policies-v1-15-76fde70fdbd8@pengutronix.de> (raw)
In-Reply-To: <20250820-security-policies-v1-0-76fde70fdbd8@pengutronix.de>
From: Ahmad Fatoum <a.fatoum@barebox.org>
To make it easier to experiment with security policies, add four example
configurations, two via the build system and two "externally".
Signed-off-by: Ahmad Fatoum <a.fatoum@pengutronix.de>
