extlinux.conf is a text file format the defines a menu of bootable OSs. It's a (de-facto I suppose) standard that's implemented by extlinux (if indeed that is a piece of SW:-) and also U-Boot and barebox and likely other bootloaders too.
So, when U-Boot locates extlinux.conf on disk and processes it, it's parsing a configuration file/menu, not chain-loading/executing another bootloader.
I see, so shouldn't we document then who is in charge of its format at least, before we start making a U-boot/distro specific version of it?
The content of the file is documented at:
http://www.freedesktop.org/wiki/Specifications/BootLoaderSpec/
... although extlinux.conf is a single file containing all the entries, rather than a separate *.conf per OS. I'm not sure where that aspect of the file is documented. Dennis, do you know where?
FWIW, the concept of a single file rather than many *.conf has been embodied in U-Boot's pxe and sysboot commands for some time, and isn't anything to do with this patch set.
