[oe] RFC: Kexec Cmdline Support

[Hans Henry von Tresckow]

(sorry for crossposting this,but I think more of the interested parties read
oe-devel then angstrom-devel)

A while back, mwester made some patches to add the ability to modify the
cmdline when using kexec to load a kernel. I did some testing on poodle and
posted the results on the bug tracker
(http://bugs.openembedded.org/show_bug.cgi?id=2969)
I was wondering what the rest of the developers think of these. I would like
to see them incoprorated in one way or another, since this will allow us to
support booting a root-fs directly from the SD card. This is especially
important for flash-challenged devices (collie, poodle, sl-c700) but also
makes testing new images much simpler.

Thank you for your time,

Henry von Tresckow (hvontres)
