Subject: [PATCH v2 2/8] hw/arm/exynos4210: Specify explicitly the GIC has 64 external IRQs
Date: Wed, 12 Feb 2025 16:43:27 +0100	[thread overview]
Message-ID: <20250212154333.28644-3-philmd@linaro.org> (raw)
In-Reply-To: <20250212154333.28644-1-philmd@linaro.org>

When not specified, Cortex-A9MP configures its GIC with 64 external
IRQs (see commit a32134aad89 "arm:make the number of GIC interrupts
configurable"). Add the GIC_EXT_IRQS definition (with a comment)
to make that explicit.

Except explicitly setting a property value to its same implicit
value, there is no logical change intended.
