Subject: [RFC PATCH 11/11] target/mips: Remove I6500 CPU definition
Date: Fri,  9 Feb 2024 10:05:12 +0100	[thread overview]
Message-ID: <20240209090513.9401-12-philmd@linaro.org> (raw)
In-Reply-To: <20240209090513.9401-1-philmd@linaro.org>

I6500 support is incomplete as it lacks SAAR (Special Address
Access Register) and DSPRAM (Data Scratch Pad RAM) features.
