Hello,

I would like to download dtc for linux 2.6.26 (powerpc). But the link on the
ozlab homepage is dead.
Where can I download it ?

Thanks
Sébastien

Recent kernel versions have dtc included:

http://lxr.linux.no/linux+v2.6.25/arch/powerpc/boot/dtc-src/

If you want to make my-board.dtb, just type:

$ make my-board.dtb

You may need to specific DTS_FLAGS though, e.g.:

$ export DTS_FLAGS="-p 0x1000"
$ make my-board.dtb

What do those flags do, by the way?  (Is there documentation I should read on 
this?)

I've skimmed Documentation/powerpc/booting-without-of.txt a bit, but I don't 
recall it mentioning much about flags?  (A quick grep showed gpio flags and 
address allocation flags, but not what any of them actually _were_...)

dtc --help will give you a brief summary

The -p 0x1000 option causes dtc to add 0x1000 bytes of padding to the
emitted tree structure.  That means the bootloader can add a few
nodes/properties to the blob without having to reallocate it.
