I couldn't get the echo > /dev/xxx to work. I had to write a small app
that opened the device and write and read characters for testing.
Start there and you may find it is actually working.

Are there efforts in this area or is it already working for powerpc? I
cross compiled kexec and tried it on an old kernel with kexec support
compiled in.
/var # ./kexec -t elf -l zImage.elf
get_memory_ranges(): Unsupported platform
Could not get memory layout

Is there any work being proposed/done in this area? I'm looking at the
drivers/serial/cpm_uart files and see no support for sync/HDLC SCCx
channels. Can anyone offer some history or insight to this area?

I've got an mpc8270 running the fs_enet v1.0 driver and we are having

kernel with the 8260_io driver (kernel is from the denx ELDK4.2)
