Unable to boot? Missing EspRamdisk upstream

[kallisti5]

The documentation mentions "EspRamdisk" + linux.iso seemingly packaged within the u540.fd, however upstream tianocore edk2-platform doesn't seem to have any of this code / functionality.

Since no disk / block devices appear to be supported by tianocore u540, it appears loading anything with the tianocore edk2 is impossible at the moment?

Oh you're right. I was meant to upstream that, too. I don't expect t hat to be easy, so I didn't do that initially. Edk2 is okay but you need a different edk2-platforms branch: https://github.com/riscv/riscv-edk2-platforms/commits/devel-boot-kernel

I think this branch doesn't have any extra changes but if it doesn't work with upstream edk2, try this: https://github.com/riscv/riscv-edk2/commits/devel-boot-kernel
