i have ported linux2.6.23 to mpc860t board use cpm smc1 as serial port.
when i boot my kernel with ramdisk i find it stop after print"Loading Ramdisk to 07e20000, end 07fa4100 ... OK"
i paste the logbuf as follow(include some test info),bootargs=/dev/ram rw. if i set the bootargs=console=ttyCPM0,9600 root=/dev/ram rw my kernel stop at the console setup period.

You do need to have the 'console=ttyCPM0..." line. The system is
booting, so you are most of the way there. The next step is to find
out *where* it is failing and try to get a backtrace. If you've got a
debugger you can try halting the processor to see where the PC is
stuck. That will tell you if you are stuck on a infinite loop
somewhere, or if the CPM driver is causing an oops. (Look in
System.map for executable code addresses)
Cheers,

Could you try the patches from git://git.bocc.de/dbox2.git ppc-fixes i
submitted recently?
You might as well download the series (the patches starting with
PATCH#2) from
http://patchwork.ozlabs.org/linuxppc-embedded/list?person=1023
Thanks,
Jochen

Oops, the related patches are already in 2.6.23, please disregard the
mail above.

Or better yet, use paulus's git tree which has most of the above
patches, as well as several other patches relevant to 8xx. Note that
there are some device tree changes you'll need to make -- look at the
mpc885ads dts.

You do need to have the 'console=ttyCPM0..." line. The system is
booting, so you are most of the way there. The next step is to find
out *where* it is failing and try to get a backtrace. If you've got a
debugger you can try halting the processor to see where the PC is
stuck. That will tell you if you are stuck on a infinite loop
somewhere, or if the CPM driver is causing an oops. (Look in
System.map for executable code addresses)
Cheers,
