How to boot Arria 10 from SD card?

We have an Alaric Arria10 dev kit which currently has u-boot, device tree binary, and zImage in the QSPI, and the rootfs in the SD-card.

The SD-card partitions and rootfs contents are custom, not the default ones provided by the Alaric dev kit.

Our goal is to eliminate the QSPI and boot entirely from the SD-card.

How do I put the contents of the QSPI into the SD-card and make the SD-card bootable?

The Alaric dev kit reference manual only has instructions for QSPI.

I have brief experience with Cyclone V, and these files were put into the first partition, which was a FAT32 partition.

I'd prefer to just move binaries around, but I can force myself to rebuild uboot if needed.

Any pointers would be welcome.

thanks
