[U-Boot-Users] Uboot Device Tree

[reckless]

Hi,

I am using the u-boot-1.2 on powerpc. I am using separate device tree
compiled by DTC. 
Is there any way to embed the device tree in uboot i.e auto generate the
device tree?
What is libftd? i didnt get any links or details about that? I search the
CONFIG_OF_LIBFDT macro in the u-boot source and i didn't find it any where?

Do anyone have any idea?

Regards
Manish Sharma

Hi Manish,

You need to upgrade to the latest u-boot, LIBFDT is a relatively recent 
addition.  The "tip of the tree" in git (and soon to be released 1.3) 
has libfdt support, 1.2 does not.  The support is expected to improve 
over the next couple of months, but what we have is functional.
