Nowadays, chipsets or boards do not only have one USB port with the
capabilities of a debug port but several ones. Some of these ports are
easier accessible than others, so making them configurable is also necessary.
This change adds infrastructure to switch between EHCI controllers,
but does not implement it for any chipset.

On AMD platforms, setting of USBDEBUG_DEFAULT_PORT=0 tries to scan
all physical ports one after other in incrementing order. To avoid
possible problems with other USB devices, one can select the port
number here and bypass the scan.
Intel platforms can communicate with usbdebug dongle on one
physical port only, and this option makes no difference there.

All the additional work that needs to be done in EHCI BAR relocation
is independent of the hardware platform and was functionally identical
in all the copies removed.
When USBDEBUG is not selected, PCI EHCI controllers use standard
pci_dev_read_resources() call.
With USBDEBUG selected, PCI EHCI controller's device_operations
.read_resources is replaced with pci_ehci_read_resources() call,
which in turn will replace the device_operations .set_resources call.
The replacement for .set_resources reconfigures usbdebug driver side,
and calls the original .set_resources to configure hardware side.

Therefore, setting the xHCI BAR to 0xe8001000 worked the same like
setting it to 0xe8000000, as bit12 is reserved and ignored. This again
interfered with the MMIO space of the first EHCI controller and broke
S3 resume on Ivy Bridge.
AFAIK, the MRC ignores the setting of the xHCI BAR, anyway. So just drop

On newer Intel systems, the flash ROM is shared between the host
processor (BIOS), it's Management Engine (ME) and an integrated ethernet
controller (GbE). The layout of the flash ROM (and other information) is
kept in the so called Intel Firmware Descriptor (IFD). If we only want
to build coreboot to update the BIOS section, all we need is the flash
layout.
This patch adds the option to specify the flash layout in the
mainboard's Kconfig, and thus, to build without the real IFD. However,
with such a build, one has to make sure that the IFD section on the
flash ROM won't be written over (nor any other section that hasn't been
included by coreboot). A patch to write selected sections of a flash ROM
with IFD has been sent to the flashrom mailing list [1].

There is assorted magic setup necessary for the devices and
while it is similar for each device there are subtle differences
in some register settings.
These devices must be put into "ACPI Mode" in order to take
advantage of S0ix. When in ACPI mode the allocated PCI BARs
must be passed to ACPI so it can be relayed to the OS. When
the devices are in ACPI mode BAR0+BAR1 is saved into ACPI NVS
and then updated and returned when the OS calls _CRS.
Note that is is not entirely complete yet. We need to update
the IASL compiler in our build environment to support ACPI 5.0
in order to be able to pass the FixedDMA entries to the kernel.
There are also no ACPI methods defined yet to do D0->D3->D0
transitions for actually entering/exiting S0ix states.
This is hard to test right now because our kernel does not support
any of these devices in ACPI mode. I was able to build and test
the upstream bleeding-edge branch of the linux-pm git tree. With
that tree I was able to enumerate and load the driver for the
DesignWare I2C driver and attempt to probe the I2C bus -- although
there are no devices attatched.
I am also able to see the resources from ACPI in /proc/iomem get
reserved properly in the kernel.

This bit offset is incorrect and should only be set based
on another bit in a different register.

The new enable_pm1() function was doing 2 things wrong:
1. It was doing a RMW of the pm1 register. This means we were
keeping around the enables from the OS during S3 resume. This
is bad in the face of the RTC alarm waking us up because it would
cause an infinite stream of SMIs.
2. The register size of PM1_EN is 16-bits. However, the previous
implementation was accessing it as a 32-bit register.
The PM1 enables should only be set to what we expect to handle in the
firmware before the OS changes to ACPI mode.

Previously southbridge_smm_init() was provided that did both
the clearing of the SMM state and enabling SMIs. This is
troublesome in how haswell machines bring up the APs. The BSP
enters SMM once to determine if parallel SMM relocation is possible.
If it is possible the BSP releases the APs to do SMM relocation.
Normally, after the APs complete the SMM relocation, the BSP would then
re-enter the relocation handler to relocate its own SMM space.
However, because SMIs were previously enabled it is possible for an SMI
event to occur before the APs are complete or have entered the
relocation handler. This is bad because the BSP will turn off parallel
SMM save state. Additionally, this is a problem because the relocation
handler is not written to handle regular SMIs which can cause an
SMI storm which effectively looks like a hung machine. Correct these
issues by turning on SMIs after all the SMM relocation has occurred.

This reclaims space in ACPI NVS by removing unused fields and
adds new fields for SerialIO BARs which will be used to communicate
the allocated resources to ACPI.
