Exactly.  An armv5l root filesystem will run on dozens of boards.  You
need to rebuild the kernel for a specific board, but not the root
filesystem or toolchain.

The point of these system images is to encourage native development
(I.E. building software natively under qemu, optionally using distcc to
call out to a compatible cross compiler on the host).

All it needs to do this is _a_ kernel that qemu is capable of booting
that can run that software with appropriate peripherals (serial I/O,
network card, block device, RTC, etc).  It includes an example kernel
built to do that under qemu, and a shell script to launch qemu.  But
these are not kernels you'd install on the actual hardware, there are
dozens of those for each root filesystem.

There used to be one, but it's impossible to be complete.
