[PATCH 1/2] Add mkelfimage and support for generating kernel+initrd ELF payloads to OpenEmbedded
On x86, and ELF image file may be stored as a coreboot payload. This image file may be a kernel or a kernel+initrd.
Documentation on this has been started on the coreboot wiki: http://www.coreboot.org/Mkelfimage
We have seen success using the mkelfimage utility to construct a kernel+initrd image using the micro-image OpenEmbedded image as an initrd. http://www.se-eng.com/wiki/index.php/Open_Embedded_Setup
The first patch contains the meta files for the mkelfimage utility in OpenEmbedded. --- recipes/mkelfimage/files/no-stack-protector.patch | 11 +++++++++++ recipes/mkelfimage/mkelfimage-native_git.bb | 11 +++++++++++ recipes/mkelfimage/mkelfimage.inc | 3 +++ recipes/mkelfimage/mkelfimage_git.bb | 17 +++++++++++++++++ 4 files changed, 42 insertions(+), 0 deletions(-) create mode 100644 recipes/mkelfimage/files/no-stack-protector.patch create mode 100644 recipes/mkelfimage/mkelfimage-native_git.bb create mode 100644 recipes/mkelfimage/mkelfimage.inc create mode 100644 recipes/mkelfimage/mkelfimage_git.bb

Dear Raymond,
I am putting you in CC not knowing if you read the lists.

What is your build configuration for testing this recipe?
The first patch contains the meta files for the mkelfimage utility in OpenEmbedded.
Please remove that line above. The commit message should be describing the commit only.
Unfortunately we cannot commit your patch, especially because your Signed-off-by line is missing – you can add `-s` to the Git commands `git commit` or `git format-patch` and your mailer mangled the patch by automatic line breaks.
Please follow the commit policy [1] and it would be great if you could send us a corrected patch [2].
Please add a header describing this patch [3].
Here you can see an automatic line break.
Please send that patch separately to the coreboot list if it is useful for upstream. You should be able to use Gerrit and you also need a Signed-off-by line [4].
Please follow the style guide [5], i. e., no space before `()`.
`do_stage ()` is deprecated [6].
Please order those as in the style guide and please also add the `HOMEPAGE` variable.
We start with `r0`.
Not needed since this is the only recipe.
Is that needed? There is no archive as far as I know.
Thanks,
Paul

Thanks Paul. I am putting together new patches to address your feedback on style guide, mailer line-feed, and patch format/commit policy.
As far as the build configuration this was tested on is concerned, this is Ubuntu 10.04 x86_64-linux targeting i686-oe-linux using a one-off of the i686-generic.conf machine targeting a 4MB flash part.
Thanks again, Ray
