But if I can memory map the FPGA via the FMC, I can simply put an APB memory mapped QSPI controller on the FPGA and store my config there, using the same flash for the FPGA bitstream as well.

This saves a chip on the board, reduces the amount of PCB routing required, and eliminates use of the sketchy OCTOSPI peripheral entirely. Testing that out is on my list of things to do on this board eventually.

I almost always include I2C EEPROM - just too cheap and pretty easy to route.

That can't be memory mapped, so I'd need to rewrite my KVS code which currently expects to be able to return a pointer to the raw on-flash image of the config data. Doable but a pain.
