Enable support for FAT filesystem with SPL for CycloneV instead of raw
mode.
Recent changes breaks CycloneV MMC boot from raw mode, and so we are taking
this opportunity to migrate MMC boot mode to FAT as smaller OCRAM size is
required, as well as aligning MMC boot flow with our other devices.
Fixes: 2a00d73d081a1 ("spl: mmc: Try to clean up raw-mode options")

But what about other boards for the cycline5? If you want to switch,
switch them all. This looks half-backed.
BTW, the FAT refers to a u-boot.bin file on a fat partition, right? And
the SPL will be kept in the A2 raw partition then?
Yes, that’s correct. SPL remains in the raw/A2 partition as required by
the Boot ROM. U-Boot proper is moved to a FAT32 partition.
Thanks.
