Hi, Sending this out in a slightly unfinished state to gauge if there's interest in having this included in U-Boot. Basically this allows running U-Boot under QEMU's '-machine virt' emulation, thus making it possible to boot Linux distros that use the extlinux.conf booting method under '-machine virt'.
To some extent, this is currently possible by emulating and running U-Boot on some of the Versatile boards, but (IIRC) they have some limitations like limiting to 1GB of RAM or lacking support for PCI.
