Subject: [PATCH 11/16] hw/sparc: Use explicit big-endian LD/ST API
Date: Fri,  4 Oct 2024 01:42:06 +0200	[thread overview]
Message-ID: <20241003234211.53644-12-philmd@linaro.org> (raw)
In-Reply-To: <20241003234211.53644-1-philmd@linaro.org>

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