[U-Boot] Reading data from SPI flash before relocation - what is the best way to do this?

OK, the question why you don't use SPL has already been asked.

Why do you need to read it separately?  Can you not "attach" it to the
U-Boot image, so the boot ROM will read that combined image (U-Boot
plus your config data) ?
