u-boot: add Marvell u-boot.kwb support

commit: http://git.buildroot.net/buildroot/commit/?id=3cd5174ed796400a9566c0ea52f3551cba52bfe0
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Marvell boards like the sheevaplug needs a special .kwb image format, so add an option for it similar to how we handle zImage/uImage/.. for the kernel.

Just for documentation if someone searches the mailingarchive:
I run a plain vanilla u-boot with a minor patch in bin-format on my seagate dockstar (sheevaplug with less memory). But this is chainloaded by the proprietary u-boot. So at least for this configuration you are not forced to use the .kwb format.

@Peter:
Please note my patch for applying patches to u-boot. The current git tree includes a typo. I corrected it and submitted the patch more than once to the mailinglist (see attachement).

The solution is rather forward and the patch is tested (only two modified lines).

Kind regards,
Marcus

Ok. u-boot.kwb is in mainline u-boot so it isn't a big issue.

Committed, thanks.
