Duncan Laurie ae1ef60dfa falco: Update DIMM SPD table
RAM_ID indices have been changed and settled on a 2GB config
that will be the same DRAM chips but only used in one channel.

Duncan Laurie c7f2ab742b haswell: Add magic to turn on grahpics in normal mode
The haswell i915 kernel driver apparently expects the VBIOS
to set a few specific registers.  This sequence is enough to
make the driver happy without executing the VBIOS.

This also makes graphics work after suspend/resume.

Duncan Laurie 22419e0456 falco: Add on-board devices and configure GPIO irq/wake
Add the onboard I2C devices for Falco trackpad/lightsensor
and generate SMBIOS Type41 tables for them.

Add ACPI device for the trackpad to expose the interrupt map
to the OS so it can be used.

Configure interrupt GPIOs as PIRQ type and wake GPIOs as
just standard input type.  The wake GPIO is reconfigured as
ACPI SCI in the specific device _DSW method.  This prevents
the wake GPIO from generating a flood of SCI at runtime.

LTE_WAKE_L_Q and WLAN_WAKE_L_Q are left as ACPI SCI as these
are not repurposed interrupt pins so they are not generated
at runtime.

SIM_DET and ALS_INT_L are set as input since we don't have an
interrupt handler for them.

Add the onboard I2C devices for Slippy trackpad/lightsensor

tested on slippy with trackpad with additional
kernel changes to chromeos_laptop.c to initialize devices.

1) Ensure trackpad interrupt is functional and that there
is not a flood of ACPI SCI when trackpad does interrupt:
  9:          1          0          0          0   IO-APIC-fasteoi   acpi
 37:        421          0          0          0   IO-APIC-fasteoi   cyapa

2) Ensure that devices are exposed as wake capable:
Device  S-state   Status   Sysfs node
TPAD      S3    *enabled   pnp:00:00
TSCR      S3    *disabled  pnp:00:01

3) Ensure that trackpad can wake from S3 by default, but
that it does not cause an immediate wake when entering suspend.

4) Ensure that trackpad can be disabled as a wake source with
echo TPAD > /proc/acpi/wakeup

Stefan Reinauer 86ce7f9273 RTC: Skip rtc_init() in S3 resume path
In addition to not clearing the pending interrupts, we also
don't want to reset the RTC control register when booting
with an S3 resume.

On most new systems, when the RTC well is losing power, we
will also lose state that is required to perform a resume,
so we end up in a normal boot anyways. Hence don't do any
RTC initialization in the S3 resume path.

can be assigned to specific GPIOs when they are configured
as PIRQ.

The maximum redirection entries field in the IOAPIC needs to
be set to 0x27 when this is enabled.

Additionally specific GPIOs need to be routed to PIRQ so they
interrupt via the IOAPIC instead of the GPIO IRQ 14/15.

Duncan Laurie 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.

Aaron Durbin 8a0cb8de65 cbfstool: check potential microcode update earlier
The update-fit command takes in a parameter for number of slots
in the FIT table. It then processes the microcobe blob in cbfs
adding those entries to the FIT table. However, the tracking of
the number of mircocode updates was incremented before validating
the update. Therefore, move the sanity checking before an increment
of the number of updates.

Duncan Laurie 92e1f15175 lynxpoint: Expose ACPI Device for LP GPIO controller
In order to probe the gpio-lynxpoint kernel driver the
LP GPIO controller needs to be exposed as a specific
ACPI device.

This also allows the resources to be exposed to the OS via
this device instead of the catch-all LPC device.

Ensure the driver loads at boot:
gpiochip_find_base: found new base at 162
gpiochip_add: registered GPIOs 162 to 255 on device: INT33C7:00

Also ensure the driver is visible in sysfs:
$ cat /sys/devices/platform/INT33C7:00/gpio/gpiochip162/label
INT33C7:00

Gabe Black 8f4baece7a elog: Make sure the elog data structures are initialized in elog_clear.
If elog_clear is called before other elog functions, for instance if it's
called through an SMI immediately after the system boots, then the elog data
structures won't have been set up and the system will go off the deep end.
This change adds a call to elog_init to elog_clear to make sure things things
are always initialized before we start using them.

Before this change, this command would cause
the system to lock up if run immediately after boot:

echo 1 > /sys/firmware/gsmi/clear_eventlog

After this change, that results in the log being cleared correctly.

Stefan Reinauer 8c5947709a cbmem utility: compatibility with older coreboot versions
Commit b8ad224 changed the memory address in lb_cbmem_ref coreboot
table entries from a pointer to a uint64_t. This change was introduced
to make the cbmem utility work on both 32bit and 64bit userland.
Unfortunately, this broke the cbmem utility running on older versions
of coreboot because they were still providing a 32bit only field for
the address while the cbmem utility would now take the following 4
bytes as upper 32bits of a pointer that can obviously not be
mmapped. This change checks if the size of the lb_cbmem_ref structure
provided by coreboot is smaller than expected, and if so, ignore the
upper 32bit of the address read.

be supported. Attempts to build without native graphics will result in
an error.

This code builds for both x86 emulation targets. I'm hitting an issue
testing that is unrelated to coreboot; if someone can test, that
would be helpful. Be sure to start qemu with -vga std.

We also add a test for the PCI BAR being zero and return silently if it
is.
