Subject: [PATCH v3 15/18] system/physmem: Avoid cpu_physical_memory_rw when is_write is constant
Date: Tue, 30 Sep 2025 10:21:22 +0200	[thread overview]
Message-ID: <20250930082126.28618-16-philmd@linaro.org> (raw)
In-Reply-To: <20250930082126.28618-1-philmd@linaro.org>

Following the mechanical changes of commit adeefe01671 ("Avoid
cpu_physical_memory_rw() with a constant is_write argument"),
replace:

 - cpu_physical_memory_rw(, is_write=false) -> address_space_read()
 - cpu_physical_memory_rw(, is_write=true)  -> address_space_write()

Signed-off-by: Philippe Mathieu-Daudé <philmd@linaro.org>
