Serial console not working on EP8343M

[Ed Swierk]

I'm having trouble getting the serial console to work on an EP8343M
board when using U-Boot 1.2.0 to start Linux 2.6.20.1. I'm using arch
powerpc and platform MPC834x_SYS (which is perhaps wishful thinking,
as my board is different, although it should at least have the same
serial port configuration).

The symptoms are exactly the same as those in
http://ozlabs.org/pipermail/linuxppc-embedded/2006-September/024457.html:
the console stops working after the call to console_init(). The
suggested solution was to ensure that U-Boot is setting
timebase-frequency, bus-frequency and clock-frequency and passing
those properties to the kernel, and this does indeed seem to be
happening in my case.

I've attached the output from U-Boot (including a dump of the flat
device tree), as well as my kernel config and U-Boot board settings.
Any help would be appreciated.
