Yet another solution is to enable early printk via the "DCC" channel,
which should normally get the early printks to be sent to the JTAG. You
can then ask your JTAG to display the messages.

The openocd command seems to be "target_request debugmsgs charmsg". I
have never tried this on TI processors, but I have tried it on other
processors with other JTAG, which shows that at least, on Linux side, it
works.
