Taking device_t as a parameter, this allows to alter the PCI config
access handlers. This is useful to add tracing of PCI config writes
for devices having problems to initialise correctly.
On older AMD platform PCI MMIO may not be able to fully configure all
PCI devices/nodes, while MMIO_SUPPORT_DEFAULT would be preferred due
to its atomic nature. So those can be forced to IO config instead.

Here's the great news: From now on you don't have to worry about
hitting the right io.h include anymore. Just forget about romcc_io.h
and use io.h instead. This cleanup has a number of advantages, like
you don't have to guard device/ includes for SMM and pre RAM
anymore. This allows to get rid of a number of ifdefs and will
generally make the code more readable and understandable.
Potentially in the future some of the code in the io.h __PRE_RAM__
path should move to device.h or other device/ includes instead,
but that's another incremental change.

We used to allow mainboards to override subsystems using
mainboard_pci_subsystem_vendor_id and mainboard_pci_subsystem_device_id.
Mechanisms have changed and the only occurrence of these names is in
the header.

We thought about two ways to do this change. The way we decided to try
was to
1. drop all ops from devices in romstage
2. constify all devices in romstage (make them read-only) so we can
compile static.c into romstage
3. the device tree "devices" can be used to read configuration from
the device tree (and nothing else, really)
4. the device tree devices are accessed through struct device * in
romstage only. device_t stays the typedef to int in romstage
5. Use the same static.c file in ramstage and romstage
We declare structs as follows:
ROMSTAGE_CONST struct bus dev_root_links[];
ROMSTAGE_CONST is const in romstage and empty in ramstage; This
forces all of the device tree into the text area.
So a struct looks like this:
static ROMSTAGE_CONST struct device _dev21 = {
#ifndef __PRE_RAM__
.ops = 0,
#endif
.bus = &_dev7_links[0],
.path = {.type=DEVICE_PATH_PCI,{.pci={ .devfn = PCI_DEVFN(0x1c,3)}}},
.enabled = 0,
.on_mainboard = 1,
.subsystem_vendor = 0x1ae0,
.subsystem_device = 0xc000,
.link_list = NULL,
.sibling = &_dev22,
#ifndef __PRE_RAM__
.chip_ops = &southbridge_intel_bd82x6x_ops,
#endif
.chip_info = &southbridge_intel_bd82x6x_info_10,
.next=&_dev22
};

PCI Type 2 config was a strange and never-used config mechanism.
It is unlikely that in the 13 years of coreboot's existence that
type 2 was ever used; it just made life complicated for everyone.
It lived long enough in coreboot to be replaced by mmioconf.
Prior to making the device tree visible in romstage we want to
get rid of type2.
Delete two files we don't need any more (yay!).
Replace two functions with one: pci_config_default, which returns
a pointer to the default config method. At some future time this
may change to mmio but for now it is old type1 style.

Many PCI devices share the very same driver despite having different
PCI device IDs, which causes a lot of copy and paste of driver
definitions.
This change introduces a way to specify the array of acceptable
device IDs in a single driver entry. As an example the Intel
{Sandy|Ivy} Bridge SATA driver is being modified to use a single
driver structure for all different SATA controller flavors, a few
more Ivy Bridge IDs are being added as well.
BUG=none
TEST=manual
. modified coreboot brought up an Ivy Bridge platform all the
way to Linux login screen.

Also:
- Improve a few code comments, fix typos, etc.
- Change a few more variable types to u8/u16/u32 etc.
- Make some very long lines fit into 80chars/line.
- Drop a huge duplicated comment, use "@see" to refer to the other one.
- Reduce nesting level a bit by restructuring some code chunks.
- s/Config.lb/devicetree.cb/ in a few places.
Abuild-tested.

- Add static and const where possible.
- Turn some #warning entries into TODO comments.
- Add missing prototypes.
- Remove unused variables.
- Fix printf arguments or cast them as needed.
- Make sconfig output look better. Drop useless "PARSED THE TREE" output.
- Print "(this may take a while)" while building romcc. Add missing "\n".

during early coreboot_ram), pci_{read,write}_config{8,16,32} will die().
This patch changes pci_{read,write}_config{8,16,32} to use the existing
PCI access method autodetection infrastructure instead of die()ing.
Until r4340, any usage of pci_{read,write}_config{8,16,32} in
coreboot_ram before the device tree was set up resulted in either a
silent hang or a NULL pointer dereference. I changed the code in r4340
to die() properly with a loud error message. That still was not perfect,
but at least it allowed people to see why their new ports died.
Still, die() is not something developers like to see, and thus a patch
to automatically pick a sensible default instead of dying was created.
Of course, handling PCI access method selection automatically for
fallback purposes has certain limitations before the device tree is set
up. We only check if conf1 works and use conf2 as fallback. No further
tests are done.
This patch enables cleanups and readability improvements in early
coreboot_ram code:
Without this patch:
dword = pci_cf8_conf1.read32(&pbus, sm_dev->bus->secondary,
sm_dev->path.pci.devfn, 0x64);
With this patch:
dword = pci_read_config32(sm_dev, 0x64);

- Added support for having different versions of the pci access functions
on a per bus basis if needed.

- Rename chip_config chip_operations throughout the tree
- Fix Config.lb on most of the Opteron Ports
- Fix the amd 8000 chipset support for setting the subsystem vendor and device ids
- Add detection of devices that are on the motherboard (i.e. In Config.lb)
- Baby step in getting the resource limit handling correct, Ignore fixed resources
- Only call enable_childrens_resources on devices we know will have children
For some busses like i2c it is non-sense and we don't want it.
- Set the resource limits for pnp devices resources.
- Improve the resource size detection for pnp devices.
- Added a configuration register to amd8111_ide.c so we can enable/disable individual ide channels
- Added a header file to hold the prototype of isa_dma_init
- Fixed most of the superio chips so the should work now, the via superio pci device is the exception.
- The code compiles and runs so it is time for me to go to bed.
