Booting HPS from FPGA

Hello, has anyone managed to boot the whole u-boot image (Bootloader) from FPGA? If so, how did you do this? There are tutorials for booting the HPS from FPGA with U-Boot SPL. The tutori...

The actual U-Boot's size is 1553 Kbytes, so that doesn't fit into our device's On-Chip memory. Would it be possible to add Ethernet support to the U-Boot SPL? Or to use the UEFI bootloader? Arria 10 seems to support the UEFI bootloader. Is there support also for Cyclone V?
