hi all,

After some problem with my custom board and kernel 2.6.19 about the
init process, i've moved
on 2.6.23 and that had fixed my problems. (related to this post :
http://marc.info/?l=linuxppc-embedded&m=119609022221017&w=2)
Apparently it was a problem with cpm_uart on SMC1.
(http://lkml.org/lkml/2007/9/23/99)
the patch have been integrated in 2.6.23. Now i use this kernel and
busybox works.
I want to migrated my board in powerpc branch instead of ppc (i plan
to use xenomai but in 2.6.23
there is only an adeos patch for piowerpc branch), but i see the use
of a device tree
instead of bd_t struct. I'm a bit disappointed because i also see that
older u-boot (in my case
ppcboot 1.1.5) aren't capable to pass dts to kernel.
Is there a way to keep my old bootloader to boot a powerpc branch kernel ?

Yes, you can build a 'cuImage' in arch/powerpc which wraps the kernel
image with a device tree and copies the bd_t data into the tree before
booting.

Cheers,
g.
