ab365af0a0 lynxpoint: implement additional programming steps
The BIOS spec for LynxPoint calls out additional
programming steps for the PCIe Root Ports. Implement those
steps from the BIOS spec. These steps are completed before
deeper PCIe probing. The "late" programming was removed as
that was applicable to Cougar/Panther point where this
code was originally copied, though there was some overlap.

c0254e6b6f lynxpoint: disable pcie devices based on config
PCIe Root Ports should be disabled based on pin ownership
and the strapping configuration. Implement this logic
for LynxPoint. The chip_ops->enable_dev() path is no
longer used. Instead the PCIe driver handles the enabling
and disabling of devices. This allows for having an empty
or incomplete device tree since those "allocated" devices
do not travel through the chip_ops->enable_dev() path.
The coalescing was tested to be working properly, however
not all configurations were tested.

3fcd356464 lynxpoint: expose pch_disable_devfn()
The function to disable devices was formerly named
pch_hide_devfn(). This routine was doing more than hiding
devices. It was disabling them, i.e. turning them off.
Therefore, rename it to pch_disable_devfn(). Also, allow
external callers to this function.

Additionally they both have specific requirements when entering

has steps for S4/S5 entry.

- GPIO route to SCI
- GPIO config to GPIO, Input, Inverted

d7cb8d074f lynxpoint: Change SerialIO device enable reporting to ACPI
In order to report whether coreboot enabled a SerialIO device
in ACPI mode we had been relying on reading NVS in the _STA
method for the SerialIO device.

The ACPI _STA method has restrictions on what it can access
and is unable to access OperationRegions outside its scope
which means it should not be trying to read NVS.

This change adds a new SSDT to the ACPI tables and fills it
with constants that indicate whether or not a device is enabled
in ACPI mode.

The ACPI code is changed to read these variables from the
SSDT and use that instead of trying to query a variable in NVS.

Attempt to use lpt-clk driver to probe the
device clocks for SerialIO devices and see that the kernel
does not complain about accessing the GNVS region.

to use this.

Also fix a bug in the LP version of get_gpio() that was always

fb387dfb92 usbdebug: Drop duplicates of EHCI BAR relocation code
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.

The ACPI NVS region was setup in place and there was a CBMEM
table that pointed to it.  In order to be able to use NVS
earlier the CBMEM region is allocated for NVS itself during
the LPC device init and the ACPI tables point to it in CBMEM.

The current cbmem region is renamed to ACPI_GNVS_PTR to
indicate that it is really a pointer to the GNVS and does
not actually contain the GNVS.

b39ba2efcf lynxpoint: Basic configuration of SerialIO devices
This adds configuration of SerialIO devices in the Lynxpoint-LP
chipset.  This includes DMA, I2C, SPI, UART, and SDIO controllers.

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.

d6d6db3717 lynxpoint: fix enable_pm1() function
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.
