U-Boot SPL on the generic RISC-V CPU supports two boot flows, directly jumping to the image and via OpenSBI firmware. In the first case, both U-Boot SPL and proper must be compiled to run in the same privilege mode. Using OpenSBI firmware, U-Boot SPL must be compiled for machine mode and U-Boot proper for supervisor mode. To be able to use SPL, boards have to provide a supported SPL boot device.
