+Subject: serial: 8250_pci: Add Realtek 816a and 816b
+
+From: Tobias Diedrich <tobiasdiedrich@gmail.com>
+
+commit 3c5a87be170aba8ac40982182f812dcff6ed1ad1 upstream.
+
+These serial ports are exposed by the OOB-management-engine on
+RealManage-enabled network cards (e.g. AMD DASH enabled systems using
+Realtek cards).
+
+Because these have 3 BARs, they fail the "num_iomem <= 1" check in
+serial_pci_guess_board.
+
+I've manually checked the two IOMEM regions and BAR 2 doesn't seem to
+respond to reads, but BAR 4 seems to be an MMIO version of the IO ports
+(untested).
+
+With this change, the ports are detected:
+0000:02:00.1: ttyS0 at I/O 0x2200 (irq = 82, base_baud = 115200) is a 16550A
+0000:02:00.2: ttyS1 at I/O 0x2100 (irq = 55, base_baud = 115200) is a 16550A
