I can not speak for this particular board, but for others with the
same SoC (AT91SAM9G20). The vendor approach is to setup the SDRAM
(and maybe more) in at91bootstrap, however those old SoCs are not
supported in recent version 4.x of that anymore, 3.x should work, I
never tried that for sam9g20 (we still use 1.x for those SoCs).
at91bootstrap then usually loads U-Boot from flash to SDRAM and starts
U-Boot.
You can do the same init in U-Boot SPL as well without the "real"
at91bootstrap, I think I saw that for other boards with similar SoCs.
And from what I saw here, barebox has the concept of multiple stages
as well, right? So SDRAM must be initialized there in the very first
stage after ROM code running from (tiny) internal SRAM, equivalent to
what at91bootstrap does, before relocating to SDRAM. There's no magic
thing the ROM code can do for you on that platform.
