The FSPS component loading was just loading to any memory address
listed in the header. That could be anywhere in the address space
including ramstage itself -- let alone corrupting the OS memory on
S3 resume. Remedy this by loading and relocating FSPS into cbmem.
The UEFI 2.4 header files include path are selected to provide the
types necessary for FSP relocation.

The previously implementation for loading the FSPM component didn't
handle platforms which expects FSPM to be XIP. For the non-XIP case,
romstage's address space wasn't fully being checked for overlaps.
Lastly, fixup the API as the range_entry isn't needed any longer.
This API change requires a apollolake to be updated as well.

Instead of performing the same tasks in the chipset code move
the common sequences into the FSP 2.0 driver. This handles the
S3 paths as well as saving and restoring the memory data. The
chipset code can always override the settings if needed.

The amount of reserved memory just below the DRAM limit in
32-bit space is defined in the FSP 2.0 specification within
the FSPM_ARCH_UPD structure. There's no need to make the
chipset code set the same value as needed for coreboot.
The chipset code can always change the value if it needs
after the common setting being applied.
Remove the call in soc/intel/apollolake as it's no longer
needed.

The interrupt and timer subsystem (ITSS) sits between the APIC
and the other logic blocks. It only supports positive polarity
events, but there's a polarity inversion setting for each IRQ such
that it can pass the signal on to the APIC according to the
expected APIC redirection entry values. This support is needed
in order for the platform/board to set the expected interrupt
polarity into the APIC for gpio signals.

Internally, apollolake routes its interrupts as active high.
This includes SCI, SMI, and ACPI. Therefore, provide helper
macros such that the user can describe an interrupt's active
high/low polarity more easily. It helps for readability when
one is comparing gpio configuration next to APIC configuration
in different files. Additionally, the gpio APIC macros always
use a LEVEL trigger in order to let the APIC handle the
filtering of the IRQ on its own end.

evaluates to an integer, the value is the bit assignment of the SCI

There is a second ACPI _DSD document from the UEFI Forum that details
how _DSD style tables can be nested, creating a tree of similarly
formatted tables. This document is linked from acpi_device.h.
In order to support this the device property interface needs to be
more flexible and build up a tree of properties to write all entries
at once instead of writing each entry as it is generated.
In the end this is a more flexible solution that can support drivers
that need child tables like the DA7219 codec, while only requiring
minor changes to the existing drivers that use the device property
interface.
This was tested on reef (apollolake) and chell (skylake) boards to
ensure that there was no change in the generated SSDT AML.

Add the Audio DSP device for apollolake as a PCI driver with a static
scan_bus handler so generic devices can be declared under it.
This is for devices like the Maxim 98357A which is connected on the
I2S bus for data but has no control channel bus and instead just has
a GPIO for channel selection and power down control and needs to
describe that GPIO connection to the OS via ACPI.

The P2SB device is device 0xd and function 0. If hidden that
causes the latter pci devices on function >= 1 to not be probed
in the kernel. This is also a problem for coreboot if the P2SB
device is hidden by FSP. That means the coreboot driver won't
be ran. Therefore, provide hide and unhide functions for the
P2SB device.
The other quirk is to allow the GPIO devices to work correctly.
Those devices are ACPI devices. However, their resources are
sub-regions within the P2SB BAR. Sadly, linux doesn't handle
ACPI devices being children of PCI devices. This leads to resource
conflict errors when the P2SB device is visible. For the
time being keep the P2SB device hidden, but also ensure the
resources it is using are accounted for and reserved. The fallout
of that is the PMC and SPI device are no longer probed by the
kernel.
BUG=chrome-os-partner:53017
TEST=Ensured P2SB device is visible and pci resources are allocated
correctly for the devices.

There are four GPIO communities in this SOC and they are implemented
as separate ACPI devices. This means the pin number that is used in
an ACPI GPIO declaration needs to be relative to the community that
the pin resides in. Also select GENERIC_GPIO_LIB in the SOC Kconfig
so this function actually gets used.
This was tested on the reef mainboard by verifying the output of the
SSDT for the Maxim 98357A codec that the assigned GPIO_76 is listed
as pin 0x24 which is the value relative to the Northwest community.

Support the I2C interfaces on this SOC using the Intel common lpss_i2c
driver. The controllers are supported in pre-ram environments by
setting a temporary base address in bootblock and in ramstage using
the naturally enumerated base address.
The base speed of this controller is 133MHz and the SCL/SDA timing
values that are reported to the OS are calculated using that clock.
This was tested on a google/reef board doing I2C transactions to the

Have the Skylake SOC generate ACPI timing values for the enabled I2C
controllers instead of passing it in the DSDT with static timings.
The timing values are generated from the controller clock speed and
are more accurate than the hardcoded values that were in the ASL which
were originally copied from Broadwell where the controller is running
at a different clock speed...
Additionally it is now possible for a board to override the values
using devicetree.cb. If zero is passed in for SCL HCNT or LCNT then
the kernel will generate its own timing using the same forumla, but if
the SDA hold time value is zero the kernel will NOT generate a correct
value and the SDA hold time may be incorrect.
This was tested on the Chell platform to ensure all the I2C devices on
the board are still operational with these new timing values.

spi_init should be run early enough in ramstage so that any init
calls (e.g. mainboard_ec_init) that write on flash have right
permissions set.

Bootblock:
- Temporary BAR needs to be assigned for SPI device until PCI
enumeration is done by ramstage which allocates a new BAR.
- Call spi_init to allow bootblock/verstage to write/erase on flash.
Ramstage:
- spi_init needs to run in ramstage to allow write protect to be
disabled for eventlog and NVRAM updates. This needs to be done pretty
early so that any init calls(e.g. mainboard_ec_init) writing to flash
work properly.
Verified with this change that there are no more flash write/erase
errors for ELOG/NVRAM.

This I2C controller has separate registers for different speeds to set
specific timing for SCL high and low times, and then a single register
to configure the SDA hold time.
For the most part these values can be generated based on the freq of
the controller clock, which is SOC-specific. The existing driver was
generating SCL HCNT/LCNT values, but not the SDA hold time so that is
added.
Additionally a board may need custom values as the exact timing can
depend on trace lengths and the number of devices on the I2C bus. This
is a two-part customizaton, the first is to set the values for desired
speed for use within firmware, and the second is to provide those
values in ACPI for the OS driver to consume.
And finally, recent upstream changes to the designware i2c driver in
the Linux kernel now support passing custom timing values for high
speed and fast-plus speed, so these are now supported as well.
Since these custom speed configs will come from devicetree a macro is
added to simplify the description:
register "i2c[4].speed_config" = "{
LPSS_I2C_SPEED_CONFIG(STANDARD, 432, 507, 30),
LPSS_I2C_SPEED_CONFIG(FAST, 72, 160, 30),
LPSS_I2C_SPEED_CONFIG(FAST_PLUS, 52, 120, 30),
LPSS_I2C_SPEED_CONFIG(HIGH, 38, 90, 30),
}"
Which will result in the following speed config in \_SB.PCI0.I2C4:
Name (SSCN, Package () { 432, 507, 30 })
Name (FMCN, Package () { 72, 160, 30 })
Name (FPCN, Package () { 52, 120, 30 })
Name (HSCN, Package () { 38, 90, 30 })
