You need to make sure your FSBL matches the dts/dtb you are used. I am using hybrid images. I use FSBL + PMU from the system I generated and ATF + U-boot + kernel + rootfs + dtb from meta-xilinx. I create the vivado design base on the DTS. I did have some changes to u-boot and kernel dts. This will give full working system. IRC, MMC + sata is not working for me with SPL.
