The Arria10 uses slightly different boot image header than the Gen5 SoCs, in particular the header itself contains an offset from the start of the header to which the Arria10 jumps. This offset must not be negative, yet the header is placed at offset 0x40 of the bootable binary. Therefore, to jump into U-Boot, add a trampoline just past the Arria10 boot header and point to this trampoline at fixed offset from the header generated using the mkimage -T socfpgaimage_v1 . Note that it is not needed to jump back to offset 0x0 of the image, it is possible to jump directly at the reset label and save processing two instructions.
