Subject: [PATCH 07/16] target/m68k: Use explicit big-endian LD/ST API
Date: Fri,  4 Oct 2024 01:42:02 +0200	[thread overview]
Message-ID: <20241003234211.53644-8-philmd@linaro.org> (raw)
In-Reply-To: <20241003234211.53644-1-philmd@linaro.org>

The M68K architecture uses big endianness. Directly use
the big-endian LD/ST API.
