I additionally have "tty0 c 4 0" which might be important here, plus a lot of other crap (should clean up there...;-). I don't use a ramdisk, but have the /dev folder in the flash jffs2 image. In the init script, I say
/bin/mount -t tmpfs ramfs /dev
mdev -s
mkdir /dev/pts
mkdir /dev/shm
chmod 1777 /dev/shm
and then tty0 is gone. So to be honest I'm not absolutely sure it's necessary.
My inittab contains
::sysinit:/etc/init.d/rcS
::respawn:-/bin/sh
::shutdown:/etc/init.d/rcS stop
::restart:/sbin/init
::respawn:/sbin/dropbear -F
With this, I can access the board through ssh (dropbear). The dmesg output lists "console=tty0" as expected. All PSC's are in the device tree, btw, and available as serial ports.
Hth,
Albrecht.
