dfadd9edff PCI/x86: detect host bridge config space size w/o using quirks
Many host bridges support a 4k config space, so check them directy
instead of using quirks to add them.

We only need to do this extra check for host bridges at this point,
because only host bridges are known to have extended address space
without also having a PCI-X/PCI-E caps.  Other devices with this
property could be done with quirks (if there are any).

As a bonus, we can remove the quirks for AMD host bridges with family
10h and 11h since they're not needed any more.

With this patch, we can get correct pci cfg size of new Intel CPUs/IOHs
with host bridges.

821508d4ef x86: move a few device initialization objects into .devinit.rodata
Impact: debuggability and micro-optimization

Putting whatever is possible into the (final) .rodata section increases
the likelihood of catching memory corruption bugs early, and reduces
false cache line sharing.

824877111c x86, pci: move arch/x86/pci/pci.h to arch/x86/include/asm/pci_x86.h
Impact: cleanup

Now that arch/x86/pci/pci.h is used in a number of other places as well,
move the lowlevel x86 pci definitions into the architecture include files.
(not to be confused with the existing arch/x86/include/asm/pci.h file,
which provides public details about x86 PCI)

Tested on: X86_32_UP, X86_32_SMP and X86_64_SMP

12c0b20fa4 x86/PCI: use dev_printk when possible
Convert printks to use dev_printk().

I converted DBG() to dev_dbg().  This DBG() is from arch/x86/pci/pci.h and
requires source-code modification to enable, so dev_dbg() seems roughly
equivalent.

b6ce068a12 Change pci_raw_ops to pci_raw_read/write
We want to allow different implementations of pci_raw_ops for standard
and extended config space on x86.  Rather than clutter generic code with
knowledge of this, we make pci_raw_ops private to x86 and use it to
implement the new raw interface -- raw_pci_read() and raw_pci_write().

346ca04d05 PCI: re-enable onboard sound on "MSI K8T Neo2-FIR"
On the "MSI K8T Neo2-FIR" board the BIOS disables the onboard
soundcard, if a second PCI soundcard is present.

This patch sets the korrect register bit to enable the onboard sound.

Removed old code in /drivers/pci/quirks.c that only checks for the
PCI-ID and fires on any Board with VIA 8237.

New code in /arch/i386/pci/fixup.c checks the DMI-tables and only runs
on the specific board.
