Hi,
I was able to boot the first cuImage build from a 2.6.23-rc7 kernel source
on my AmigaOne. Unfortunately the kernel triggers a BUG_ON statement in
of_get_flat_dt_root(), which is called in the probe function of my
platform code.
I wasn't able to capture the kernel log, but it looks similar to
+#if defined(CONFIG_VIOTAPE) || defined(CONFIG_VIOTAPE_MODULE)
+/* Handle interrupt events for tape */
+static void __init handle_tape_event(struct HvLpEvent *event)

This adds cpu_setup functionality for ppc44x platform.
Low level cpu-spefic initialization routines should be
placed in cpu_setup_44x.S and a callback should be
added to cputable. The cpu_setup is invoked
by identify_cpu() function at early init.

The PowerPC 440EP(x) FPU init is currently done in head_44x
under ifdefs. Since we should support more then one board
in the same kernel, we move FPU initialization code from head_44x
to cpu_setup_44x and add cpu_setup callbacks for 440EP(x).

Add a workaround for PowerPC 440EPx/GRx incorrect write to

in SDRAM when write pipelining enabled on plb0. We disable
it in the cpu_setup for these processors at early init.
