[Qemu-ppc] Can qemu support uImage and tar.gz as input kernel and root filesystem image formats

[Elvis Dowson]

Hi,
      Can qemu accept other types of images for the kernel and rootfilesystem, 
apart from a vmlinux and ext3 file system? 

For example, can it accept a uImage and a tar.gz image as input for the kernel 
image and rootfilesystem?

At the moment, my yocto core-image-minimal and core-image-sato builds the 
following files, if I first build with machine ?= "virtex5", and then 
subsequently with machine ?= "qemuppc"

core-image-minimal-virtex5-20120603201342.rootfs.tar.gz

vmlinux-qemuppc.bin

Is it possible to use the uImage-virtex5.bin for the kernel image and 
core-image-minimal-virtex5.tar.gz as the rootfilesystem, instead of 
vmlinux-qemuppc.bin and core-image-sato-qemuppc.ext3 ?

Best regards,
