Subject: [PATCH v2 2/4] arm64: dts: Foundation model: increase GICC region to allow EOImode=1
Date: Tue, 15 Dec 2015 13:36:36 +0000 [thread overview]
Message-ID: <1450186598-24504-3-git-send-email-andre.przywara@arm.com> (raw)
In-Reply-To: <1450186598-24504-1-git-send-email-andre.przywara@arm.com>
The Foundation model GIC mapping is wrong, as the GICC region should
be 8kB instead of 4kB (the model implements the GICv2 architecture).
This defect prevents the driver from switching to EOImode==1.
