Note when we've found a 8250 PNP node. Only try to set hw.uart.console if we see one (otherwise ignore serial hints). The 8250 is the only one known to have I/O ports, so limit the guessing to when we've positively seen one. And limit this to x86 since that's the only platform where we have I/O ports. Otherwise, we'd set the serial port to something crazy for the platform and fall off the cliff early in boot. Differential Revision: https://reviews.freebsd.org/D16463 |
