Subject: [PATCH 4/9] arm: socfpga: agilex5: fix read of memory limit
Date: Thu, 16 Apr 2026 11:48:08 +0200 [thread overview]
Message-ID: <20260416-socfpga-agilex5-sdram-v1-4-07556aa7219f@pengutronix.de> (raw)
In-Reply-To: <20260416-socfpga-agilex5-sdram-v1-0-07556aa7219f@pengutronix.de>
FW_MPU_DDR_DMI0_SCR_READL adds the base address to the register address.
Drop it from the caller to avoid adding the base address twice.
