Subject: [PATCH 3/6] target/mips: Initialize CPU-specific timer/IRQs once in DeviceRealize
Date: Tue, 21 Jan 2025 17:18:14 +0100	[thread overview]
Message-ID: <20250121161817.33654-4-philmd@linaro.org> (raw)
In-Reply-To: <20250121161817.33654-1-philmd@linaro.org>

The MIPS timer and IRQs are tied to the CPU. Creating them outside
in board code isn't correct. Do it once in the DeviceRealize() handler.
