Which has nothing to do with uImage.
A uImage is a historic u-boot container format containing a Linux zImage
(also often called a "vmlinuz"), which was booted using the "bootm"
command. This is no longer needed and the zImage can be booted directly
with the u-boot "bootz" command.

Maybe this platform had a bootloader which needed a uImage, that is not
the common case today and is certainly not the case with sunxi.

I mean the Debian Installer, the development of which is the subject of
the debian-boot list where this thread originated and the thing which
Karsten was posting patches against.
The current daily builds of Debian Installer for the next version of
Debian can be found at:
http://ftp.debian.org/debian/dists/testing/main/installer-armhf/current/images/armmp/netboot/
initrd.gz and vmlinux-foo in there can be booted as is on sunxi (and
many other armv7 systems) from the u-boot prompt using bootz, or using
PXE or (on sunxi) by using FEL.
If you want to hijack this thread to talk about some other thing which
you want to call "debian installer" then please leave me out of it.
Ian.
