Subject: [PATCH v2 2/9] buildsys: Remove support for 32-bit MIPS hosts
Date: Wed, 15 Oct 2025 14:38:36 -0700	[thread overview]
Message-ID: <20251015213843.14277-3-richard.henderson@linaro.org> (raw)
In-Reply-To: <20251015213843.14277-1-richard.henderson@linaro.org>

From: Philippe Mathieu-Daudé <philmd@linaro.org>

Stop detecting 32-bit MIPS host as supported, update the
deprecation document. See previous commit for rationale.
