I've tried to port my exesting configurations to the powerpc tree but
some configurations files are missing.
I need to set PSC3 - PSC4 in uart mode:
before in file *arch/ppc/platforms/lite5200.c* I added
struct mpc52xx_psc_func mpc52xx_psc_functions[] = {
{ .id = 3,

First, create a new .dts file for your board in arch/powerpc/boot/dts.
(just copy the lite5200.dts file). Mo
Ok, maybe it's better to start from the beginning.
Now I'm using a Lite5200b board, just to avoid problems with my
hardware, and I'm trying to have a bootable kernel.
With kernel version 2.6.24.6 I do the following commands
$ make ARCH=powerpc lite5200_defconfig
$ make ARCH=powerpc CROSS_COMPI

Hello!
I've seen you guys are playing with a Lite5200b board, so I've decided
to do another attempt with mine.

Nice to hear that, next week I'll try and let you know.
Thank you again for your support,

Hello,
in uboot i have setting the bootargs variable:
=> bootargs debug console=ttyPSC0,115200 root=/dev/ram
=> saveenv
If I'm not wrong, the right sequence of commands should be the following:
$ make ARCH=powerpc mpc5200_defconfig
$ make ARCH=powerpc menuconfig
.. [customizations]...
$ make A

Hi Grant,
I've tried to add that with this commands
=> bootargs debug console=ttyPSC0,115200 root=/dev/ram
=> save
