This patch series addresses configuration corrections and enables required features for SD/eMMC support on the SoCFPGA Agilex5 platform.
Summary of changes: 1. Remove SDIO_SEL GPIO hog configuration The SDIO_SEL GPIO hog setup is removed as voltage switching is now managed by the regulator framework, allowing proper UHS-I voltage control through the MMC subsystem. 2. Correct SDHCI controller node from SD4HC to SD6HC Updates the device tree to use the Cadence SD6HC controller (replacing SD4HC), adds appropriate compatible strings, and configures voltage regulators and GPIOs for SD card I/O switching. 3. Enable MMC and Cadence SDHCI support in defconfig Enables the MMC subsystem and Cadence SDHCI driver in both SPL and U-Boot proper, including ADMA and regulator support, to provide SD card functionality and voltage regulation. 4. Add dedicated eMMC device tree and defconfig Adds device tree and configuration for eMMC operation on Agilex5, including fixed I/O voltage regulator and timing parameters for supported modes. These changes are specific to the SoCFPGA Agilex5 platform and ensure correct SD/eMMC controller configuration and feature enablement. Please review and provide feedback.
