The Kconfig symbol SERIAL_S3C2412 got removed in commit
da121506eb03ee5daea55404709110b798bd61d9 ("serial: samsung: merge
probe() function from all SoC specific extensions"). But it also added a
last reference to that symbol. The commit and the tree make clear that
CPU_S3C2412 should have been used instead.

With commit 835d844d1 (8250_pnp: do pnp probe before legacy probe), the 8250 driver was renamed to 8250_core. This means any existing usage of the 8259.<xxxx> module parameters or as a kernel command line switch is now broken, as the 8250_core driver doesn't parse options belonging to something called "8250". To solve this, we redefine the module options in a dummy function using a redefined MODULE_PARAM_PREFX when built into the kernel. In the case where we're building as a module, we provide an alias to the old 8250 name. The dummy function prevents compiler errors due to global variable redefinitions that happen as part of the module_param_ macro expansions.

This could have been either ARCH_S5P64X0 or CPU_S5P6450. Looking at
commit 2555e663b367b8d555e76023f4de3f6338c28d6c ("ARM: S5P64X0: Add UART
serial support for S5P6450") - which added this typo - makes clear this
should be CPU_S5P6450.

The InsydeH2O BIOS (version dated 09/12/2011) has the following in its pnp resouces for its serial ports: $ cat /sys/bus/pnp/devices/00:0b/resources state = active io disabled irq disabled We do not check if the resources are disabled, and create a bogus ttyS* device. Since commit 835d844d1a28e (8250_pnp: do pnp probe before legacy probe) we get a bogus ttyS0, which prevents the legacy probe from detecting it. Note, the BIOS can also be upgraded, fixing this problem, but for people who can't do that, this fix is needed.

I've managed to find an 8 port version of the card 4 port card which was discussed here: http://marc.info/?l=linux-serial&m=120760744205314&w=2 Looking back at that thread there were two issues in the original patch. 1) The I/O ports for the UARTs are within BAR2 not BAR0. This can been seen in the original post. 2) A serial quirk isn't needed as these cards have no memory in BAR0 which makes pci_plx9050_init just return. This patch fixes the 4 port support to use BAR2, removes the bogus quirk and adds support for the 8 port card. $ lspci -vvv -n -s 00:08.0 00:08.0 0780: 10b5:9050 (rev 01) Subsystem: 10b5:1588 Control: I/O+ Mem- BusMaster- SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx- Status: Cap+ 66MHz- UDF- FastB2B+ ParErr- DEVSEL=medium >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx- Interrupt: pin A routed to IRQ 17 Region 1: I/O ports at ff00 [size=128] Region 2: I/O ports at fe00 [size=64] Region 3: I/O ports at fd00 [size=8] Capabilities: <access denied> Kernel driver in use: serial $ dmesg | grep 0000:00:08.0: [ 0.083320] pci 0000:00:08.0: [10b5:9050] type 0 class 0x000780 [ 0.083355] pci 0000:00:08.0: reg 14: [io 0xff00-0xff7f] [ 0.083369] pci 0000:00:08.0: reg 18: [io 0xfe00-0xfe3f] [ 0.083382] pci 0000:00:08.0: reg 1c: [io 0xfd00-0xfd07] [ 0.083460] pci 0000:00:08.0: PME# supported from D0 D3hot [ 1.212867] 0000:00:08.0: ttyS4 at I/O 0xfe00 (irq = 17) is a 16550A [ 1.233073] 0000:00:08.0: ttyS5 at I/O 0xfe08 (irq = 17) is a 16550A [ 1.253270] 0000:00:08.0: ttyS6 at I/O 0xfe10 (irq = 17) is a 16550A [ 1.273468] 0000:00:08.0: ttyS7 at I/O 0xfe18 (irq = 17) is a 16550A [ 1.293666] 0000:00:08.0: ttyS8 at I/O 0xfe20 (irq = 17) is a 16550A [ 1.313863] 0000:00:08.0: ttyS9 at I/O 0xfe28 (irq = 17) is a 16550A [ 1.334061] 0000:00:08.0: ttyS10 at I/O 0xfe30 (irq = 17) is a 16550A [ 1.354258] 0000:00:08.0: ttyS11 at I/O 0xfe38 (irq = 17) is a 16550A Signed-off-by: Scott Ashcroft <scott.ashcroft@talk21.com> Cc: stable <stable@vger.kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
