On Chrome OS systems a memory setting change is needed to be deployed
without updating the FSP blob proper. Under such conditions one needs
to trigger retrain of the memory. For ease of use provide an option,
FSP_PLATFORM_MEMORY_SETTINGS_VERSIONS, which incorproates the SoC
and mainboard memory setting version number into the FSP version
passed to the platform. The lower 8 bits of the FSP version are the
build number which in practice is normally 0. Use those 8 bits to
include the SoC and mainboard memory settings version. When FSP,
SoC, or mainboard memory setting number is bumped a retrain will be
triggered.

The devicetree data structures have been available in more than just
ramstage and romstage. In order to provide clearer and consistent
semantics two new macros are provided:
1. DEVTREE_EARLY which is true when !ENV_RAMSTAGE
2. DEVTREE_CONST as a replacment for ROMSTAGE_CONST
The ROMSTAGE_CONST attribute is used in the source code to mark
the devicetree data structures as const in early stages even though
it's not just romstage. Therefore, rename the attribute to
DEVTREE_CONST as that's the actual usage. The only place where the
usage was not devicetree related is console_loglevel, but the same
name was used for consistency. Any stage that is not ramstage has
the const C attribute applied when DEVTREE_CONST is used.

The SD/MMC support is broken into several pieces. There are three main
data structures:
* sdhci_ctrlr - This is SDHCI controller specific and defined in
include/device/sdhci.h
* sd_mmc_ctrlr - This contains generic controller management data and
defined in include/device/sd_mmc_ctrlr.h
* storage_media - This contains the flash storage device management data
and is defined in include/device/storage.h
The SD/MMC driver consists of several components:
* SDHCI controller code
* bouncebuf.c
* bouncebuf.h
* pci_sdhci.c
* sdhci.c
* sdhci.h
* sdhci_adma.c
* sdhci_display.c
* Flash storage device support
* mmc.c
* mmc.h
* sd.c
* sd_mmc.c
* sd_mmc.h
* storage.c
* storage.h
* storage_erase.c
* storage_write.c
Kconfig values enable various portions of the controller and storage
drivers to be built to reduce the overall size of what is included in
the final image.
Full read/write/erase operations are provided for those platforms which
want to take advantage. It is also possible to build the driver to
perform initialization only. By default, this driver is not included in
any platform, platforms must specifically select DRIVERS_STORAGE to add
the SD/MMC support.
After this patch is reviewed and merged, there are some additional
patches:
* Common CAR storage area - Use a predefined region of CAR to pass data
structures between bootblock through to romstage. This allows early
stages to preform the SD/MMC device initialization and later stages
to use the SD/MMC device without further initialization. The example
code initializes the SD/MMC device in bootblock and uses the SD/MMC
device in romstage without further initialization.
* CBMEM ID - Add a CBMEM ID value for the data structures so that they
may be passed from romstage to ramstage and eventually the payload.
The example uses the SD/MMC device in ramstage without further
initialization.
* Move the SD/MMC driver into commonlib
* Have libpayload build the SD/MMC driver from commonlib. The intent
is to pass the controller state to libpayload so that the SD/MMC
device can be used without further initialization.
* On some platforms, have depthcharge use the commonlib SD/MMC driver
History:
Copy the SD/MMC driver from depthcharge revision eb583fa8 into coreboot
and make the following changes:
* Removed #include "config.h" from mmc.c, allow the lint tests to pass.
* Move include files from drivers/storage into include/device.
* Rename mmc.h to storage.h.

The Cr50 TPM uses an IRQ to provide a "status" signal used for hand-shaking
the reception of commands. Real IRQs are not supported in firmware,
however firmware can still poll interrupt status registers for the same
effect.
Commit 94cc485338 ("drivers/i2c/tpm/cr50: Support interrupts for status")
added support for the Cr50 driver on X86 platforms to use a KConfig file
to supply an IRQ which it would poll using acpi_get_gpe. If the IRQ is
not supplied, the Cr50 driver inserts a 20 ms wait.
Unfortunately this doesn't work so well when using the i2c connected Cr50
on ARM platforms. Luckily, a more generic implementation to allow a
mainboard to supply a Cr50 IRQ status polling function was solved for SPI
connected Cr50s by commit 19e3d335bd ("drivers/spi/tpm: using tpm irq to
sync tpm transaction").
Let's refactor the i2c c50 driver to use this same approach, and change
eve and reef boards to make use of DRIVER_TPM_TIS_ACPI_INTERRUPT for
specifying the TPM flow control interrupt.
This essentially reverts these two commits:
48f708d199 drivers/i2c/tpm/cr50: Initialize IRQ status handler before probe
94cc485338 drivers/i2c/tpm/cr50: Support interrupts for status
And ports this commit to i2c/tpm/cr50:
19e3d335bd drivers/spi/tpm: using tpm irq to sync tpm transaction
As a side effect the tpm_vendor_specific IRQ field goes back to its
original usage as the "TPM 1.2 command complete" interrupt, instead of
being repurposed to hold the flow control IRQ.

In builds without CONFIG_VBOOT_SEPARATE_VERSTAGE, verstage files are
linked directly into the bootblock or the romstage. However, they're
still compiled with a separate "libverstage" source file class, linked
into an intermediate library and then linked into the final destination
stage.
There is no obvious benefit to doing it this way and it's unclear why it
was chosen in the first place... there are, however, obvious
disadvantages: it can result in code that is used by both libverstage
and the host stage to occur twice in the output binary. It also means
that libverstage files have their separate compiler flags that are not
necessarily aligned with the host stage, which can lead to weird effects
like <rules.h> macros not being set the way you would expect. In fact,
VBOOT_STARTS_IN_ROMSTAGE configurations are currently broken on x86
because their libverstage code that gets compiled into the romstage sets
ENV_VERSTAGE, but CAR migration code expects all ENV_VERSTAGE code to
run pre-migration.
This patch resolves these problems by removing the separate library.
There is no more difference between the 'verstage' and 'libverstage'
classes, and the source files added to them are just treated the same
way a bootblock or romstage source files in configurations where the
verstage is linked into either of these respective stages (allowing for
the normal object code deduplication and causing those files to be
compiled with the same flags as the host stage's files).
Tested this whole series by booting a Kevin, an Elm (both with and
without SEPARATE_VERSTAGE) and a Falco in normal and recovery mode.

This reuses some of gm45 code to set up the panel.
Panel start and stop delays and pwm frequency can now be set in
devicetree.
Linux does not make the difference between 945gm and gm45
for panel delays, so it is safe to assume the semantics of those
registers are the same.
The core display clock is computed according to "Mobile Intel 945
Express Chipset Family" Datasheet.
This selects Legacy backlight mode since most targets have some smm
code that rely on this.
This sets the same backlight frequency as vendor bios on Thinkpad X60
and T60.
A default of 180Hz is selected for the PWM frequency if it is not
defined in the devicetree, this might be annoying for displays that
are LED backlit, but is a safe value for CCFL backlit displays.

Add support for using GPIO IRQ instead of PIRQ with an I2C device.
This allows a device to use an edge triggered interrupt that will
trigger on both high and low transitions.
The _DSD method for describing these GPIOs has a field for 'active
low' which is supposed to be 1 if the pin is active low, otherwise
is zero. The value in here doesn't mean too much for GpioInt() as
those will end up using the value from GpioInt() when it actually
requests the interrupt.
