An issue about sp5100 watchdog

[Huang Rui]

Hi all,

I found an issue in some of AMD platforms about sp5100, that the MMIO
address (0x51413120) is already used by System RAM
(00100000-7c2befff)...

[   29.928096] sp5100_tco: SP5100/SB800 TCO WatchDog Timer Driver v0.05
[   29.928302] sp5100_tco: PCI Vendor ID: 0x1022, Device ID: 0x790b, Revision ID: 0x4a
[   29.928319] sp5100_tco: Got 0x51413120 from indirect I/O
[   29.928323] sp5100_tco: MMIO address 0x51413120 already in use
[   29.928332] sp5100_tco: SBResource_MMIO is disabled(0xe000a0)
[   29.928333] sp5100_tco: failed to find MMIO address, giving up.

00100000-7c2befff : System RAM
  01000000-017b1ab3 : Kernel code
  017b1ab4-01d4ce7f : Kernel data

7cbbf000-7cbfefff : ACPI Tables
7cbff000-7cbfffff : System RAM

Any idea?

Thanks,
Rui
