Add dedicated device tree support for eMMC configuration on the Agilex5 SoCDK board, providing an alternative to the default SD card setup. Changes to socfpga_agilex5.dtsi: - - Configure always-on regulator for stable eMMC operation New device tree files: - socfpga_agilex5_socdk_emmc.dts: Main eMMC device tree configuration * Configure for eMMC operation (no-sd, no-sdio, non-removable) * Set 8-bit bus width and high speed capability * Add timing parameters for legacy and SDR modes * Configure voltage supplies for eMMC power and I/O * Add fixed 1.8V regulator for eMMC I/O voltage supply - socfpga_agilex5_socdk_emmc-u-boot.dtsi: U-Boot specific additions * Include common Agilex5 U-Boot configurations * Set SPL boot order with eMMC support * Enable necessary peripherals for boot-time operation Configuration files: - configs/socfpga_agilex5_emmc_defconfig: eMMC-specific configuration * Inherit from base Agilex5 configuration * Disable GPIO regulator support (not needed for fixed eMMC setup) * Set eMMC-specific device tree Build system integration: - Add socfpga_agilex5_socdk_emmc.dtb target to Makefile Signed-off-by: Tanmay Kathpalia <tanmay.kathpalia@altera.com> Reviewed-by: Tien Fong Chee <tien.fong.chee@altera.com>
