Uh oh, is this copying something the U-Boot SPL cannot do for us ?
Though U-Boot SPL can do, it will need 64KB onchip memory. While the EPCS controller needs only 512B onchip memory. So we didn't ever consider SPL for nios2.
Where did that 64KB figure come from ? :O
I assume the simple loader is just a copy loop, huh ? And you synthesise a small RAM or ROM into the FPGA and point NIOS to boot from that, right? What about U-Boot TPL, can that cook the loader ? (yes, I'd like to be as independent of the external code as possible).
