d44221f9c8 Move compiler.h to commonlib
Its spreading copies got out of sync. And as it is not a standard header

Some Windows and BSD quirk handling went into the util copies. We always
guard from redefinitions now to prevent further issues.

Linux has a driver that enables features like speed shift without
consulting ACPI.  Other OSes instead rely on this information and need a
_CPC present. Prior to this change performance in Win10 never exceeds
80% and MSR 0x770 is 0, while with this change (and enabling eist) higher
speeds can be achieved and the MSR value is now 1.

bf713b04b6 soc/intel: Add support for USB ACPI code generation
To support generating USB devices in ACPI the platform needs to
know how to determine a device name for each USB port, and for
any root hubs that may be present.

Recent Intel platforms route all ports to an XHCI controller
through a root hub.  This is supported by considering the root
hub to be USB port type 0, the USB 2.0 ports to be type 2, and
the USB 3.0 ports to be type 3.

This was tested with a Kaby Lake platform by adding entries to
the devicetree and checking the resulting SSDT.

fd50b7c3d7 soc/intel: Fix MCFG end bus number
The ACPI MCFG table is generated with a static end bus number of 255,
which expects that the reserved range in E820 is 256MB.  However the
actual MCFG range is configurable with Kconfig, so these two values
may not match when the OS tries to determine the range:

PCI: MMCONFIG for domain 0000 [bus 00-ff] at [mem 0xe0000000-0xefffffff] (base 0xe0000000)
PCI: MMCONFIG 0000 [bus 00-3f] at [mem 0xe0000000-0xe3ffffff] (base 0xe0000000) (size reduced!)
acpi PNP0A08:00: [Firmware Info]: MMCONFIG for domain 0000 [bus 00-3f] only partially covers this bridge

Instead of forcing the end bus number to be 255 use the Kconfig value
to set it based on the current configuration.

Tested on a fizz device to ensure that the kernel no longer complains:

PCI: MMCONFIG for domain 0000 [bus 00-3f] at [mem 0xe0000000-0xe3ffffff] (base 0xe0000000)

93bbd41ea8 soc/intel: Enable ACPI DBG2 table generation
Enable the ACPI DBG2 table generation for Intel boards.  This is
a Microsoft defined ACPI extension that allows an OS to know what
the debug port is on a system when it is not enabled by the
firmware, so it does not show up in the coreboot tables and
cannot be easily found by a payload.

broadwell: Use byte access device, set up only when enabled since
it relies on the port being put in byte access mode and using
this serial port for debug was not standard in this generation.

skylake: Enable for the configured debug port.  Skylake uses
intelblocks for UART but not ACPI.

common: Enable for the configured debug port.  This affects
apollolake and cannonlake.

Tested by compiling for apollolake/broadwell, tested by reading
the DBG2 ACPI table on kabylake board and using IASL to dump:

1fe32d6bb2 soc/intel/skylake: Split AC/DC settings for Deep Sx config
Currently when enabling Deep S3 or Deep S5 it unconditionally gets enabled
in both DC and AC states.  However since using Deep S3 disables some
expected features like wake-on-USB it is not always desired to enable the
same state in both modes.

To address this split the setting and add a separate config for Deep Sx in
AC and DC states.

All motherboards that set this config were updated, but there is no actual
change in behavior in this commit.

kernel would assume the presence of 8042 based on the

this, CONFIG_NO_FADT_8042 was added to selectively

3bfe3404df intel/skylake: Add support to enable wake-on-usb attach/detach
Three things are required to enable wake-on-usb:
1. 5V to USB ports should be enabled in S3.
2. ASL file needs to have appropriate wake bit set.
3. XHCI controller should have the wake on attach/detach bit set for the
corresponding port in PORTSCN register.

Only part missing was #3.

This CL adds support to allow mainboard to define a bitmap in
devicetree corresponding to the ports that it wants to enable
wake-on-usb feature. Based on the bitmap, wake on attach/detach bits in
PORTSCN would be set by xhci.asl for the appropriate ports.

6c1bf27dae intel/skylake: disable ACPI PM Timer to enable XTAL OSC shutdown
Keeping ACPI PM timer alive prevents XTAL OSC shutdown in S0ix
which has a power impact.

Based on a DT variable, this patch disables the ACPI PM timer
late in the boot sequence - disabling earlier will lead to a hang
since the FSP boot flow needs this timer. This also hides the ACPI PM
timer from the OS by removing from FADT table. Once the ACPI PM timer
is disabled, TCO gets switched off as well.
