There's no users of vbe_mode_info_valid() aside from the local
compilation units. Remove the declaration and make the function
static to the current global implementers.

For some reason the "interface" for adding framebuffer information
is sitting in src/include/vbe.h while also guarding the call to
fill_lb_framebuffer() with vbe_mode_info_valid() along with some
macro if CONFIG_* for good measure.
Move the fill_lb_framebuffer() declaration to coreboot_tables.h and
provide a comment about how it should be used. Also, now that
there's no need for the notion of a global vbe_mode_info_valid()
remove it from the conditional call path of fill_lb_framebuffer().

We have several different UART implementations of which three support a
timeout when receiving characters. In all of these three implementations
there is a bug where when the timeout is hit the last received character
will be returned instead of the needed 0.
The problem is that the timeout variable i is decremented after it has
been checked in the while-loop. That leads to the fact that when the
while-loop is aborted due to a timeout i will contain 0xffffffff and not
0. Thus in turn will fool the following if-statement leading to wrong
return value to the caller in this case. Therefore the caller will see a
received character event if there is none.

spi_crop_chunk is a property of the SPI controller since it depends
upon the maximum transfer size that is supported by the
controller. Also, it is possible to implement this within spi-generic
layer by obtaining following parameters from the controller:
1. max_xfer_size: Maximum transfer size supported by the controller
(Size of 0 indicates invalid size, and unlimited transfer size is
indicated by UINT32_MAX.)
2. deduct_cmd_len: Whether cmd_len needs to be deducted from the
max_xfer_size to determine max data size that can be
transferred. (This is used by the amd boards.)

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.

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 94cc485338a3 ("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 19e3d335bddb ("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.

Some renamings force us to update our code:
* Scan_Ports() moved into a new package Display_Probing.
* Ports Digital[123] are called HDMI[123] now (finally!).
* `Configs_Type` became `Pipe_Configs`, `Config_Index` `Pipe_Index`.
Other noteworthy changes in libgfxinit:
* libgfxinit now knows about ports that share pins (e.g. HDMI1 and
DP1) and refuses to enable any of them if both are connected
(which is physically possible on certain ThinkPad docks).
* Major refactoring of the high-level GMA code.

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.

The selection of the SSC reference frequency for LVDS was based on a
completely unrelated clock.
The `ssc_freq` flag should be set when the SSC reference runs at a
different frequency than the general display reference clock (DREF).
For most platforms, there is no choice, i.e. for i945 and gm45 the SSC
reference always differs from the display reference clock (i945: 66Mhz
SSC vs. 48MHz DREF; gm45: 100MHz SSC vs. 96Mhz DREF), for Nehalem and
newer, it's the same frequency for SSC/non-SSC (120MHz). The only,
currently supported platform with a choice seems to be Pineview, where
the alternative is 100MHz vs. the default 96MHz.

Linux kernel expects that power management with ACPI should always be
handled using PowerResource. However, some kernel drivers (e.g. ELAN
touchscreen) check to see if reset gpio is passed in by the BIOS to
decide whether the device loses power in suspend. Thus, until the kernel
has a better way for drivers to query if device lost power in suspend,
we need to allow passing in of GPIOs via _CRS as well as exporting
PowerResource to control power to the device.
Update mainboards to export reset GPIO as well as PowerResource for

Currently car_stage_entry is defined only in romstage_after_verstage and
as a result when SEPARATE_VERSTAGE is not selected, there is no

The solution is move out romstage_after_verstage.S from fsp1.1 driver
to skylake/romstage. And add CONFIG_PLATFORM_USES_FSP1_1 to fix the
build and boot issue with this change.
Besides that, rename the romstage_after_verstage to romstage_c_entry

We've found that the SLB9645 TPM sometimes seems to randomly start
returning 0xFF bytes for all requests. The exact cause is yet unknown,
but we should try to write our TIS code such that it avoids bad
interactions with this kind of response (e.g. any wait_for_status()
immediately succeeds because all "status bits" are set in the response).
At least for status and burstCount readings we can say for sure that the
value is nonsensical and we're already reading those in a loop until we
get valid results anyway, so let's add code to explicitly discount 0xFF
bytes.

SPI_ATOMIC_SEQUENCING was added to accomodate spi flash controllers with
the ability to perform tx and rx of flash command and response at the
same time. Instead of introducing this notion at SPI flash driver layer,
clean up the interface to SPI used by flash.
Flash uses a command-response kind of communication. Thus, even though
SPI is duplex, flash command needs to be sent out on SPI bus and then
flash response should be received on the bus. Some specialized x86
flash controllers are capable of handling command and response in a
single transaction.
In order to support all the varied cases:
1. Add spi_xfer_vector that takes as input a vector of SPI operations
and calls back into SPI controller driver to process these operations.
2. In order to accomodate flash command-response model, use two vectors
while calling into spi_xfer_vector -- one with dout set to
non-NULL(command) and other with din set to non-NULL(response).
3. For specialized SPI flash controllers combine two successive vectors
if the transactions look like a command-response pair.
4. Provide helper functions for common cases like supporting only 2
vectors at a time, supporting n vectors at a time, default vector
operation to cycle through all SPI op vectors one by one.

There was an assumption that all SPI controllers could
consume a full page of data to write. However, that
assumption doesn't hold when spi_crop_chunk() indicates
sizes smaller than page size. If the requested offset isn't
page aligned from the start then writes will fail corrupting
data since a page boundary isn't honored.
The spansion driver needed quite a bit more work to honor
the spi_crop_chunk() result. It now mimics the other
driver's code. Also, needed to add spi_crop_chunk() to
marvell/bg4cd SoC to make google/cosmos build. SPI obviously
doesn't work on that platform, but it fixes the build error.
