[-- Attachment #1.1: Type: text/plain, Size: 13662 bytes --]

Hi,

Actually, I have posted two emails, one for mpc83xx compilation error and
other for mpc85xx support to mailing list.
I have got response only for mpc85xx email. Anyway, the compilation problem
is common for both mpc83xx and mpc85xx.
Sorry for inconvenience created by me..

I have changed subject to "mpc83xx" instead "mpc85xx", and continue compile
error in this email.
I will post new request for "support of kexec for mpc85xx", if required.

"Makefile.libfdt" file is not present in the package.

I have used following link to download package.
http://www.kernel.org/pub/linux/kernel/people/horms/kexec-tools/testing/kexec-tools-2.0.2-rc1.tar.gz

No this is fine, I'm just trying to make sure I understand exactly what
you are doing.

It looks like this package is missing stuff. My only advice here is to
use git instead. I just tested GIT HEAD and the file is included and the
complication works. Can you give that a shot?

Sorry about that, I have resolved this problem by including the

[-- Attachment #1.1: Type: text/plain, Size: 5902 bytes --]

Thanks for the announcement of new release.

I have successfully compiled for mpc83xx, but execution was failed with
following message
"Symbol: mem_size found cannot set".

The root cause behind it was that pul_stack and mem_size symbols are not
defined in purgatory/arch/ppc/purgatory-ppc.c file.
Correct me if i am wrong.

As i am new to git, I am going through the git user manual to sync with the
latest sources and if possible to provide code changes in patch-format..

git diff would probably suffice if you want a two-word getting started guide :-)
Please provide an appropriate description and signed-off-by line with the patch.

Once you resolve this problem does kexec work?

My patches to the list recently should address those issues.

You mean you don't want to load a new kernel you just want to reboot the
current kernel in place? I don't think that is possible nor an small
task.

Generally, it's always best to post to the list as it will get you the
most responses.

I'm not sure what version of the kernel you are working with, but as I
believe I said before you need a recent version of the kernel tree and
there is code present that might do what you are trying to do below.

For starters. You can pull Kumar's powerpc tree which should be a better
                                                         starting point:

http://git.kernel.org/?p=linux/kernel/git/galak/powerpc.git;a=summary

The default routines in this kernel should work on an 83xx if you said
the changes you made below work. But, I have not tested on the 83xx. I
think I remember someone saying it worked.
