Yes. Or, so I thought. First, I interrupt the bootstrap with <Esc>.  Then,
I load the image into RAM with 'load simpleImage.bseip 200000' then 'go
200000'.  All of which is echo'd out the serial console by the firmware.
I assumed that the low-level setups were complete.  However, in the old
ppc/boot/m8xx_tty.c there is some initialization for SMC1 and the BRG
(serial_init()).  Where should I do this in the new model?  Is
platform_specific_init() the right place?

Thanks!  I read "4 word boundary" in the manual, and assumed 16bit words.
I fixed this, but same results.  I think I have a little more init work
todo.

Yes, this is the correct IMMR address.

Thanks for your help!
