Re: RFC: Location for Device Tree Sources?

Where should we place the sources for the OF Flat Device
Tree source files?  They used to be in U-Boot, but that
isn't happening any more.

Why ? While having device-tree's in zImages is good to handle firmwares
that can't pass them, I still think that the proper thing to do is to
have the firmware provide the DT to the kernel. Did Denk decide once for
all against having DTs passed by uboot at all ? In which case, it's
probably time to consider a fork...

Ben, you are mixing two things here.

I have nothing against U-Boot  passing  the  DT  to  the  kernel.  On
contrary,  if  DT's  are  used, than I think this is how it should be
done.

It's just that I think that the DT *sources* should not  be  part  of
the  U-Boot  soutrce  tree, and that the DT should be in fact part of
the kernel images that gets booted by U-Boot.

This has been discussed before (see archives), and the agreement  (?)
was  to  use  U-Boot's multifile image format for this purpose, where
you can combine a Linux kenrel image with a DT image  into  one  file
bootable by U-Boot.

Jon's question was where the source code of the DT should be placed.

Best regards,

Wolfgang Denk
