Nevertheless it seems difficult to be consistent. Let's start with the case where a on-board device (SPI or eMMC) does not boot, and the way to save the board is to boot from an external board. And SPL on the onboard flash is damaged, but not u-boot.img. Anyway, we want that the board boots with its consistent status, that is with the pair SPL+u-boot.img. In the example I tracked, both from the SD card. This is consistent using spl_boot_device, because it does not try to boot from a different device as the one where SPL was loaded.
thanks for explanation, I'll have to find another way then, or will maintain this patch out of tree.
