Hi,
As for my device tree, I reverted back to the original version with
nothing filled in and just replaced 0xfa20 with 0xf000 as Gary
suggested earlier.
Would it be a problem to also dynamically fixup IMMR in the device tree
from U-Boot?
Cheers

Hi Detlev, it would be nice but
I'll still try to figure out how to get u-boot to fill all this in.
Got it... thanks to

I made sure that CONFIG_OF_LIBFDT and CONFIG_OF_BOARD_SETUP were both
present in u-boot-2009.03/include/configs/EP88x.h. Then
Check the clock-frequency of the CPM BRG node. If u-boot isn't setting the
memory, it's probably not setting this either.
I set the CPM BRG clock-frequency = 153609 (value obtained from
u-boot's 'brginfo' command), set my CPU clock-frequency =
1 (down from 13000) to match what
Hi guys, I've been working off your suggestions and here's my update
on where I'm at now.
For reference, attached are my current
linux-2.6-denx/arch/powerpc/boot/dts/ep88xc.dts and
u-boot-2009.03/include/configs/EP88x.h.
I might be able to help out. Scott's right. According to U-Boots

Hi Gary
Did you try 'root=ttyCPM0,9600'?
Gave that a shot just now, doesn't seem to have changed anything other
than that it now says VFS: Cannot open root device ttyCMP0,9600 or
unknown-block(2,0). But thanks for the suggestion though.
What exactly was this supposed to do? I thought that the

Hi Scott,
s/root=/console=/
I'm not quite sure what you mean by this.
Alternatively, you can set /chosen/linux,stdout-path to poin to the serial
node you want to use for the console.
If you look at the bottom of ep88xc.dts that I attached with my
previous post, I added the following:
chosen {

Thank you for clarifying.
