One other question, if i update to u-boot 1.3.4 or whatever is the latest, can i configure so that i doesn't use FDT to boot kernel ?

TIA

Maybe.

how do i make confirm this ? TIA

I believe the 4xx boards were probably not using FDT back then. You can confirm by "help bootm" -- if it only takes the kernel addy and the optional ramdisk addy, then it is non-FDT.

But whether or not u-boot is FDT capable is pretty much moot point if you are on a v2.4.x kernel, as they don't use FDT.

You don't have to configure that - it just depoends on how you boot the Linux kenrel image - either you pass a device tree address (as the third argument to the bootm command), or you don't.

True. But if your question was really "Can I have PowerPC board boot without a Device Tree?", then no, you can't unless you work really hard in the wrong direction. :-)

All PowerPC converted to using the Device Tree for booting over two years ago now.
