I have an USB port that has debug capabilities (according to the lspci output) Should I buy the one mentioned in this page http://www.coreboot.org/EHCI_Debug_Port
Yes
or can I use a normal cable to debug?
There is no normal cable to connect two host ports together and doing so would be a bad idea anyway.
Are you sure? I didn't try it yet, but according to http://www.spinics.net/lists/linux-usb/msg32912.html it should be possible to use a Linux machine as USB debug port device.
I haven't checked whether the patch (or something similar) landed in mainline.
Once I find time I wanted to try it myself, as the Abit A-S78H I am trying to port coreboot to, doesn't have serial ports, as well.
Cheers,
