Subject: [PATCH 08/13] hw/xtensa/xtfpga: Replace memcpy()+tswap32() by stl_endian_p()
Date: Mon, 30 Sep 2024 09:34:45 +0200 [thread overview]
Message-ID: <20240930073450.33195-9-philmd@linaro.org> (raw)
In-Reply-To: <20240930073450.33195-1-philmd@linaro.org>
Replace a pair of memcpy() + tswap32() by stl_endian_p(),
which also swap the value using target endianness.
Signed-off-by: Philippe Mathieu-Daudé <philmd@linaro.org>
