If you are using CONFIG_OF_FLAT_TREE _and_ "disable_of" ist likely that you see the same behaviour, because in that case the

"bootm" code

...

still uses the of-tree address (char *of_flat_tree), after

copying the

standard bd_info data to that address. You could check the pointer that is given to the kernel for

the board

...

info data (line 967, parameter 1 of (*kernel) (...)) (or change (*kernel) ((bd_t *)of_flat_tree,... to (*kernel) (kbd,...)

Regards, Torsten

This seems like a bug.

Looking at the code I'm confused how this works at all. I dont see of_flat_tree getting setting to anything at all.

Can you guys try out Grant's patch "[PATCH] Allow CONFIG_OF_FLAT_TREE to boot a non-arch/powerpc kernel" and see if that fixes the issue when building w/CONFIG_OF_FLAT_TREE enabled. His patch should make it so that a bootm w/1 or 2 args that aren't a multiimage should boot arch/ppc style.

I applied Grant's patch, I can now boot arch/ppc style (with kernel and ramdisk image) both with CONFIG_OF_FLAT_TREE defined and not defined in my board config.

Best regards,

Thomas
