Subject: [PATCH] sp5100_tco: Add SB8x0 chipset support

The current sp5100_tco driver only supports SP5100/SB7x0 chipset, doesn't
support SB8x0 chipset, because current sp5100_tco driver doesn't know that the
offset address for watchdog timer was changed from SB8x0 chipset.

The offset address of SP5100 and SB7x0 chipsets are as follows, quote from the
AMD SB700/710/750 Register Reference Guide(Page 164) and the AMD SP5100
Register Reference Guide(Page 166).

  WatchDogTimerControl 69h
  WatchDogTimerBase0   6Ch
  WatchDogTimerBase1   6Dh
  WatchDogTimerBase2   6Eh
  WatchDogTimerBase3   6Fh

In contrast, the offset address of SB8x0 chipset is as follows, quote from
AMD SB800-Series Southbridges Register Reference Guide(Page 147).

  WatchDogTimerEn      48h
  WatchDogTimerConfig  4Ch

So, In the case of SB8x0 chipset, sp5100_tco reads meaningless MMIO
address(for example, 0xbafe00) from wrong offset address, and the following
message is logged.

   SP5100 TCO timer: mmio address 0xbafe00 already in use

With this patch, sp5100_tco driver supports SB8x0 chipset, and can avoid
iomem resource conflict.

---
v1 -> v2
 -Fix typo in module description and source code.
 -Fix a bug that can't correctly determine the watchdog fired.
 -Improve syslog messages.
 -Truncate the commit log, because previous commit log is too long.

From eba48cd0f05ff7a2f82291feae169c14b61b29af Mon Sep 17 00:00:00 2001

Subject: [PATCH] PCI: Add GPL license for drivers/pci/ioapic module

Config PCI_IOAPIC turned into a tristate in commit b95a7bd70046, but no
module license is specified.  This adds the missing module license.
