for me, but i am unsure if I have broken KGDB/XMON support.
You better check it.  The reason for all of the complexity in there is to
support that.  Lots of time was spent making kgdb/xmon work correctly, and
to break it or toss it away would kinda piss me off.
....In my new my_console_write()
I must know the length of the TX buffer in the TXBD.
Why?
...But what is the TX buffer length before serial_console_setup has run(that's
when KGB/XMON is active)?
Whatever the boot rom initializes.
