I don't see any reason little endian wouldn't work; I wasn't aware that it even existed. Aside from some workarounds for kernel struct layout and other ugly ABI issues on some archs, musl is completely endian-agnostic. > Other than that, I have a few random thoughts on microblaze systems > to experiment with: > > 1.

I'd really rather figure out how to get rootfs-on-9p working and use that for all my qemu-system experimentation. > 2.
