RW flag was added to spi_slave structure to get around a requirement on
some AMD flash controllers that need to group together all spi volatile
operations (write/erase). This rw flag is not a property or attribute of
the SPI slave or controller. Thus, instead of saving it in spi_slave
structure, clean up the SPI flash driver interface. This allows
chipsets/mainboards (that require volatile operations to be grouped) to
indicate beginning and end of such grouped operations.
New user APIs are added to allow users to perform probe, read, write,
erase, volatile group begin and end operations. Callbacks defined in
spi_flash structure are expected to be used only by the SPI flash
driver. Any chipset that requires grouping of volatile operations can
select the newly added Kconfig option SPI_FLASH_HAS_VOLATILE_GROUP and
define callbacks for chipset_volatile_group_{begin,end}.
spi_claim_bus/spi_release_bus calls have been removed from the SPI flash
chip drivers which end up calling do_spi_flash_cmd since it already has
required calls for claiming and releasing SPI bus before performing a
read/write operation.

This patch enables stage cache to save ~40ms during S3 resume.
It saves ramstage in the stage cache and restores it on resume
so that ramstage does not have to reinitialize during the
resume flow. Stage cache functionality is added to postcar stage
since ramstage is called from postcar.

kernel and SMI handler is not involved in that flow. We need to
set this bit i.e. bit 15 in ACPI gpe0a register at 0x430h. The Linux
kernel before going to sleep checks what values are passed through
ASL as wake events (through _PRW), keeps those enabled only and
clears other bits in gpe0 enable registers. So we need to inform
the kernel to keep gpio_tier_sci also set as these are needed for

system goes to S3 on waking up PMC is writing default

in the previous settings being dropped. Work around FSP's

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.

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.
