Subject: [PATCH master 03/14] RISC-V: sifive: disable non-functional SPI nodes
Date: Tue, 11 Apr 2023 09:14:25 +0200	[thread overview]
Message-ID: <20230411071436.1630752-4-a.fatoum@pengutronix.de> (raw)
In-Reply-To: <20230411071436.1630752-1-a.fatoum@pengutronix.de>

For some reasons,newer QEMU versions (tested v5.2.0) trigger a load
fault at the first readl of the driver. For now disable the nodes,
until this issue is looked into.
