Subject: [PATCH] arm64: dts: arm: corstone1000-a320: Fix GIC redistributor region size
Date: Mon, 17 Aug 2026 13:56:07 -0500 [thread overview]
Message-ID: <20260817185607.1756124-1-robh@kernel.org> (raw)
The Arm Corstone1000-A320 has a GICv4 which means the redistributor
region should be 4x256KB rather than 512KB. This issue didn't become
apparent as SMP was disabled as a work-around in early versions of the
FVP.
Fixes: 87599f1843d3 ("arm64: dts: arm/corstone1000: Add corstone-1000-a320")
Signed-off-by: Rob Herring (Arm) <robh@kernel.org>
