Subject: [PATCH 03/19] hw/microblaze/s3adsp1800: Explicit CPU endianness
Date: Tue, 5 Nov 2024 14:04:15 +0100 [thread overview]
Message-ID: <20241105130431.22564-4-philmd@linaro.org> (raw)
In-Reply-To: <20241105130431.22564-1-philmd@linaro.org>
By default the machine's CPU endianness is 'big' order
('little-endian' property set to %false).
This corresponds to the default when this machine was added;
see commits 6a8b1ae2020 "microblaze: Add petalogix s3a1800dsp
MMU linux ref-design." and 72b675caacf "microblaze: Hook into
the build-system." which added:
[ "$target_cpu" = "microblaze" ] && target_bigendian=yes
Later commit 877fdc12b1a ("microblaze: Allow targeting
little-endian mb") added little-endian support, forgetting
to set the CPU endianness to little-endian. Not an issue
since this property was never used, but we will use it soon,
so explicit the endianness to get the expected behavior.
