Subject: [Qemu-devel] [PATCH v2 05/16] hw/intc/arm_gic: Add ns_access() function
Date: Thu, 30 Oct 2014 17:12:01 -0500	[thread overview]
Message-ID: <1414707132-24588-6-git-send-email-greg.bellows@linaro.org> (raw)
In-Reply-To: <1414707132-24588-1-git-send-email-greg.bellows@linaro.org>

From: Fabian Aggeler <aggelerf@ethz.ch>

Security Extensions for GICv1 and GICv2 use register banking
to provide transparent access to seperate Secure and Non-secure
copies of GIC configuration registers. This function will later
be replaced by code determining the security state of a read/write
access to a register.
