I searched the web a couple of time to get a good tutorial how to rebuild both, uboot and the kernel for the guruplug.
I always find a promising link named "Re-building the kernel and U-Boot - PlugWiki" which points to http://plugcomputer.org/plugwiki/index.php/Re-building_the_kernel_and_U-Boot#Building_U-Boot
but this link is dead and I can't find the article.
Is there anybody out there who has a current link to this article or maybe has the article to share?
Or maybe does someone have a even more current tutorial that I can use?
