QEMU 1.5 is now using dual EFI/BIOS ROMs named efi-*.rom instead of the old pxe-*.rom (which are still in use for legacy machine types). These need to be built before upgrading Fedora to QEMU 1.5, in order to avoid using binary blobs in QEMU. Bug 958865 is about packaging the edk2 tools (especially EfiRom) into Fedora.
Created attachment 742756 [details] spec file update
I think /usr/share/ipxe/efi is a better path than /usr/share/ipxe.efi... No need to update the spec anyway, whoever commits the patch can do it.
