Hello Vitaly,
I tried the Patch from Kalle Pokki
http://ozlabs.org/pipermail/linuxppc-embedded/2006-November/025108.html
but my SMC didnt work, without this patch, it works fine. I think that
the pram_base must be set the follwing way:
diff --git a/drivers/serial/cpm_uart/cpm_uart_core.c

index ea85f6a..76ab6e5 100644

}
if(idx > fsid_smc2_uart) {
with this patch it works fine :-)
