I'm curious. In my limited exposure to U-Boot, I got the impression that the split between SPL and U-Boot proper is mostly a "technical detail", usually mostly hidden from those who install it onto a device: you just take the combined U-Boot + SPL image and write it at the appropriate offset on the relevant device. And usually if SPL works, U-Boot also works. So a bit like Jonas in the recent "hotkey in SPL" patch for rockchip SoCs, I'm curious why/when we'd want to add to SPL functionality already supported from U-Boot. === Stefan
