Subject: [PATCH v2 11/24] hw/riscv: pfsoc: Enable 64-bit SDHCI system bus support
Date: Fri, 4 Sep 2026 23:57:30 +0800 [thread overview]
Message-ID: <20260904155758.3833179-12-bin.meng@processmission.com> (raw)
In-Reply-To: <20260904155758.3833179-1-bin.meng@processmission.com>
PolarFire SoC software selects 64-bit ADMA descriptors for the Cadence
SDHCI controller. The controller supports those descriptors, but the
Cadence property remains disabled by default for other integrations.
Enable the bus64bit property from the PolarFire SoC so the generic
SDHCI descriptor engine can execute 64-bit ADMA transfers.
