AIUI Sifive's most recent board and VisionFive2 have working EDK2 UEFI. VF2's is early (boots Linux, but only from mmc. No NVMe, USB or display yet), but being worked on by StarFive themselves. In the future, with OS-A Platform spec, you can expect RISC-V computers to be no different than PCs from a user perspective. Under the hood, the platform is modern, and carries none of the legacy x86 PCs do. The scope of standardization is also broader: It's not just interrupts, timers or memory map, but also things like the interfaces for Watchdogs, GPIOs are being standardized.
