This is a first cut at making bootwrapper code which will
produce a zImage compliant with the requirements set down
by ePAPR.
This is a very simple bootwrapper, taking the device tree
blob supplied by the ePAPR boot program and passing it on
to the kernel. It builds on the earlier patch to build a
This patch adds code, linker script and makefile support to allow
building the zImage wrapper around the kernel as a position independent
executable. This results in an ET_DYN instead of an ET_EXEC ELF output
file, which can be loaded at any location by the firmware and will
process its own reloca
On Book3E, MMU_NO_CONTEXT != 0, but the slice_mm_new_context()
macro assumes that it is. This means that the map of the
page sizes for each slice is always initialized to zeroes
(which happens to be 4k pages), rather than to the correct
default base page size value - which might be 64k.

Use MMU_NO_CONTEXT as the initialiser for mm_context.id on

This breaks 40x, new patch coming.

You originally submitted the support for 460ex. Can you chime in (and
review Ayman patch) please ?
[Marri] Ben sure I will review it and send you my feedback in couple of
days.

I'm unable to boot any post-2.6.38 kernel on my G5 (PowerMac7,2
with dual 1.8GHz processors). Basically the kernel hangs at varying
points before /sbin/init is started, sometimes before and sometimes
after the framebuffer has taken over the console. There are no visible
errors on the console, onl

So how do you change the loading address of the PowerPC kernel from its default
0x40 address ?
Note that the default 0x400... is the link address of the zImage wrapper
rather than the one of THE kernel.

Booting with MSI disabled does not change anything. Actually on this

We currently dont have CPU Hotplug support working on 85xx so we need to
disable Suspsend support as it will force enabling of CPU Hotplug.
arch/powerpc/kernel/built-in.o: In function `cpu_die':
arch/powerpc/kernel/smp.c:702: undefined reference to `start_secondary_resume'
make: *** [.tmp_vmlinux
When we start a cpu we use smp_ops->kick_cpu(), which currently
returns void, it should be able to fail. Convert it to return
int, and update all uses.
Convert all the current error cases to return -ENOENT, which is
what would eventually be returned by __cpu_up() currently when
it doesn't detect t
Even when no initfunc is provided.
