I've just caught up on this discussion on the armlinux mailing
list. I have the same problem :-( I'm a bit further along than
you now that I've written the beginnings of a debugger (I wish
I was joking..) The problem is in console_init, specifically the
test to see if the UART exists in serial_console_setup ...
On my hardware, and I'm guessing on yours, this doesn't exist - I
want to use the UART on the 21285....
I've tried several kernel configs which only have 21285 UART in,
but they don't build :-( Also check out PARAMS_BASE (hunt around in the
code) this struct is usually setup by the bootloader (it seems).
Hope this helps you along..
