For kgdb and Pi I would suggest running gdbserver on the Pi.

To clarify a little - you don't need one. Your Windows PC connects to
the BeagleBone via LAN cable, and you read the coreboot log with
commands in an SSH session. You log in to the BeagleBone via SSH and
remote control it.

You can save log files on the BeagleBone, and then transfer them to
the Windows PC in a number of different ways. I like to use SFTP.
