>From section 2.3.7 of the UEFI specification: > RISC-V UEFI will only be executed in machine mode. The machine mode has > the highest privilege and this mode is the only mandatory privilege level > for RISC-V platforms; all other privilege levels are optional depending > on the platform requirements. Machine mode is the first mode entered at > the power-on reset. This level is used in UEFI for low-level access to a > hardware platform.
