5e3dad6622 soc/intel/apollolake: Initialize GPEs in bootblock
Initialize the GPEs from mainboard config in bootblock, so they
can be used in verstage to query latched interrupt status.

I still left it called in ramstage just to be sure that the
configuration was not overwritten in FSP stages.

Tested by reading and reporting GPE status in a loop in verstage
and manually triggering an interrupt on EC console.

41a3fa66a0 soc/intel/apollolake: add option for SLP_S3_L assertion width
In order to provide time for the S0 rails to discharge one needs
to be able to set the SLP_S3_L assertion width. The hardware default
is 60 microcseconds which is not slow enough on most boards. Therefore
provide a devicetree option for the mainboard to set accordingly
for its needs. An unset value in devicetree results in a conservative
2 second SLP_S3_L duration.

3b0e761dd5 soc/intel/apollolake: Enable ELOG
Add in the base for ELOG for APL. Some PM events still need to be
added but the basic events are logged here. This enables the
basic functionality of ELOG for Apollolake.

09115a92f6 soc/apollolake: add GPIO SMI support
GPIOs which trigger SMIs set the GPIO_SMI_STS status bits in SMI_STS
register. This patch also sets the SMI_EN bit in enable register for
each community based on GPIOROUTSMI bit in gpio pad. When SMI on a
gpio happens status needs to be gathered on gpio number which is done
by reading the GPI_SMI_STS and GPI_SMI_EN registers.

TEST=When system is in firmware mode executing the command
     lidclose from ec console shuts down the system.

60b4618a84 soc/apollolake: Return correct wake status in _SWS
Wake status is calculated from the four pairs of gpe0 in
cbmem CBMEM_ID_POWER_STATE which is filled very early
in romstage and depends on the routing information in
PMC GPE_CFG register. Coreboot sets the proper value
of routing based on devicetree from pmc_init. But when
system goes to S3 on waking up PMC is writing default
values again in GPE_CFG which results in returning
wrong wake status in _SWS. This patch corrects that
behaviour by correcting the gpe0 pairs in cbmem after
PMC sets the routing table in resume path.

BUG=chrome-os-partner:54876
TEST=On resume through powerbtn, lidopen, keyboard press,  etc.
     we are getting proper wake status.

This patch adds the basic framework for SCI to GPE routing code.

BUG = chrome-os-partner:53438
TEST = Toogle pch_sci_l from ec console using gpioset command and
	see that the sci counter increases in /sys/firmware/acpi/interrupt
	and also 9 in /proc/interrupts.

a942bd4952 soc/apollolake/pmc: Store the ACPI bar during set_resources stage
Because the resource for the ACPI BAR is fixed, pci_dev_set_resources
does not store it to the device. This means we need to do part of the
dance to get the ACPI IO region to work after coreboot.

Of course, this BAR can be destroyed later by the OS probing it, but
at least we try to get it working out of coreboot.

717dccc3ee soc/apollolake: Handle non-standard ACPI BAR in PMC device
The ACPI BAR (BAR2 - offset 0x20) is not PCI compliant. That means
that probing may not work. In that case, a resource still needs to be
created for the BAR.

BONUS: We now avoid the need to declare the MMIO resources as fixed.
