e2f17f782f boardid: Minor clean up and standardization
Merge the different coreboot table strapping ID structures into one
because they're really just all the same, and I want to add more. Make
the signature of the board_id() function return a uint32_t because
that's also what goes in the coreboot table. Add a printk to the generic
code handling strapping IDs in ramstage so that not every individual
mainboard implementation needs its own print. (In turn, remove one such
print from fsp1_1 code because it's in the way of my next patch.)

2bc6ad3ff1 drivers/i2c/tpm/cr50: Simplify and increase init delay to 30 seconds
The Cr50 i2c driver provides separate entry points for probing and
initialization, but probing function does not really do much.

It also claims and releases locality on every coreboot stage, but
there is no need for this - locality should be definitely claimed
after reset and then it could be retained through the boot process.

On top of that the driver does not properly account for long time it
could take the Cr50 chip to come around to reset processing if TPM
reset request was posted during a lengthy TPM operation.

This patch addresses the issues as follows:

  - tpm_vendor_probe() and tpm_vendor_cleanup() become noops, kept
    around to conform to the expected driver API.
  - tpm_vendor_init() invokes a function to process TPM reset only in
    the first stage using TPM (typically verstage), the function
    checks if locality is claimed and if so - waits for it to be
    released, which indicates that TPM reset processing is over.
  - before claiming locality check if it is already taken, and if so -
    just proceed.

BRANCH=none
BUG=b:65867313, b:68729265
TEST=Verified that reef no longer hangs during EC reboot and

8727e644ea spi/tpm: claim locality just once during boot
All coreboot stages using TPM start with the same sequence: check if
locality is claimed, if so, release it by writing 'active locality'
bit, then try claiming it.

This is actually not a proper procedure: section "5.5.2.3.1 Command
Aborts" of "TCG PC Client Platform TPM Profile (PTP) Specification
Level 00 Revision 00.430 Family 2" lists overwriting active locality
status bit as a means of triggering TPM command abort.

On top of that, none of the coreboot stages releases locality, it is
enough to claim it once when device starts booting.

In fact, locality being active when the device is in verstage is most
likely due to delayed TPM reset processing by the Cr50 TPM: reset is
an asynchronous event, and is processed once current command
processing completes.

The proper procedure is to wait if locality is active until it is
released (which will happen when Cr50 processes reset) and then
proceed to claim it. This needs to happen only during verstage, other
stages using TPM are guaranteed has been claimed earlier.

BRANCH=gru

f1f67c3b75 siemens/nc_fpga: Set FW_DONE bit before jumping to payload
Once coreboot is ready and payload has been loaded a bit inside the NC
FPGA needs to be set to notify this event. As there are NC FPGAs with
different PCI device IDs save the BAR0 address in a global variable once
the driver evaluates this address. It can then be used to access the
register from the boot state machine callback without the need of searching
for all possible PCI devices again.

As this driver is only used at ramstage there is no need of using
CAR_GLOBAL for the global variable. Use a Kconfig switch to make this
feature selectable from mainboard as not every mainboard may have a FPGA
with that capability.

9a506d5c9a spi/tpm: Make sure AP properly syncs up with Cr50

* *libgfxinit* knows about the underlying PCI device now and can
  probe MMIO addresses by itself.
* The framebuffer mapping is now completely handled inside the
  library where we validate that we neither overflow
  - the stolen memory,
  - the GTT address space, the GTT itself nor
  - the aperture window (i.e. resource2 of the PCI device)
    that we use to access the framebuffer.

Other changes:

* Fixes and a quirk for DP training.
* Fix for DP-VGA adapters that report an analog display in EDID.
* Fixes for Skylake support with coreboot.
* DDI Buffer drive-strength configuration for Haswell, Broadwell and
  Skylake.
* `gfx_test` can now be run from X windows (with glitches).
* Compatibility with GCC 7 and SPARK GPL 2017.

fd0a891ee9 drv/intel/gma/opregion: fix opregion version for Windows
Although Intel's current spec[1] shows the OpRegion structure version 
as being the top 16 bits of the field, Intel's Windows drivers
require the OpRegion structure version to be in the top 8 bits of
the field when not using a VGA BIOS (eg, NGI or GOP driver).

As the Linux i915 driver only checks that the version is >= 2,
there is no change in functionality there.

This change effectively matches Intel's implementation in TianoCore,
where the version is set to 0x0200 << 16.

47dffa59f3 chromeec: Remove checks for EC in RO
This patch removes checks that ensure EC to be in RO for recovery
boot. We do not need these checks because when recovery is requested
automatically (as opposed to manually), we show 'broken' screen where
users can only reboot the device or request recovery manually.

If recovery is requested, Depthcharge will check whether EC is in RO
or not and recovery switch was pressed or not. If it's a legitimate
manual recovery, EC should be in RO. Thus, we can trust the recovery
button state it reports.

This patch removes all calls to google_chromeec_check_ec_image,
which is called to avoid duplicate memory training when recovery
is requested but EC is in RW.

d07f377872 usbdebug: Fix init and add support for postcar
It was originally designed such that if usbdebug_init() was called
before cbmem_initialize(), it would fetch the already-initialized
state from CBMEM. This changed when cbmem_find() behaviour changed
to require cbmem_initialize() to be called first. As a result,
ramstage had to reinitialize all of the EHCI controller and USB
endpoints on entry. This was slow, specially with AMD hardware
where one can scan USB ports to probe for the debug dongle.

For postcar and ramstage, move usbdebug entry such that it is
triggered from CBMEM_INIT_HOOK instead of console_init().
Side-effect of this is usbdebug console shows 'coreboot-xxx ...
starting...' line only for romstage.

Initialisation for usbdebug is never done in postcar. If you have
USBDEBUG_IN_ROMSTAGE=n, postcar will not have console output on
usb either.

While at it, fix also some other __PRE_RAM__ cases to ENV_ROMSTAGE
and alike.

77c01e1f2f drivers/intel/fsp1_1: Adjust check for FSP header revision
With FSP 1.1, all FSP blobs are forward-compatible with newer FSP 1.1
header files, so adjust the header revision check to ensure that the
FSP blob isn't newer than the header, rather than an exact version match.

This resolves a version mismatch issue with Braswell ChromeOS devices,
which ship with FSP blobs newer than the publicly-released blob (1.1.2.0),
but older than the current Braswell FSP 1.1 header (1.1.7.0).

TEST: build/boot google/cyan and edgar boards, observe no adverse
effects from using current FSP header (1.1.7.0) with the factory-
shipped FSP blobs (1.1.4.0/1.1.4.2).

029dfff30c i2c: Move to Linux like struct i2c_msg
Our current struct for I2C segments `i2c_seg` was close to being compa-
tible to the Linux version `i2c_msg`, close to being compatible to SMBus
and close to being readable (e.g. what was `chip` supposed to mean?) but
turned out to be hard to fix.

Instead of extending it in a backwards compatible way (and not touching
current controller drivers), replace it with a Linux source compatible
`struct i2c_msg` and patch all the drivers and users with Coccinelle.

The new `struct i2c_msg` should ease porting drivers from Linux and help
to write SMBus compatible controller drivers.

Beside integer type changes, the field `read` is replaced with a generic
field `flags` and `chip` is renamed to `slave`.

Patched with Coccinelle using the clumsy spatch below and some manual
changes:

* Nested struct initializers and one field access skipped by Coccinelle.
* Removed assumption in the code that I2C_M_RD is 1.
* In `i2c.h`, changed all occurences of `chip` to `slave`.

db27e3384a mb/lenovo/t*00/romstage: Switch to new hybrid driver
Get rid of old hybrid graphics driver and use the new one.

1. Disable IGD and PEG in early romstage.
 The PEG port will get disabled on devices that do not have a
 discrete GPU. The power savings are around ~1Watt.

 The disabled IGD does no longer waste GFX stolen memory.

2. Get rid of PCI driver
 The Nvidia GPU can be handled by the generic PCI driver and allows
 to use the ACPI _ROM generator for Switchable graphics.

3. Settings are stored in devicetree.
 One driver for all Lenovo hybrid graphics capable devices.

4. Add support for Thinker1 GPU power handling.
 Only boards that do use reference design 2012 are known to be
 supported. Needs test on boards that do you use reference design 2013.
 Should reduce idle power consumption when using IGD by ~5Watt.

Tested on Lenovo T430 without DGPU. PEG port is disabled.
Needs test on all devices.

d7dcc44eb9 drvs/lenovo/hybrid_graphics: Add new hybrid graphics driver
Introduce a chip_driver that uses devicetree instead of Kconfig.

The new driver has the following advantages:

* No more wasted IGD GFX stolen memory
* Can be used by T500 series
* Is even run on devices that do not have a dGPU installed
* Can disable unused PEG port on devices without dGPU (and save power)
* Use devicetree instead of Kconfig options
* Support for multiple hybrid GPIO active levels
* Support for backlight control GPIO
* Support for _ROM on Optimus capable devices

The driver is split into romstage part and ramstage part.

Every mainboard has to call the driver in romstage to get the requested
GPU state. The mainboard code then has to toggle GPU power or disable
the IGD or PEG port.

The ramstage part does handle the hygrid graphics GPIO, including
optional backlight mux GPIO. Every GPIO can have it's own active level,
as defined in devicetree. Devices are no longer disabled in ramstage.

The existing hybrid graphics driver does the same configuration and
should not interfere with this commit until it has been removed.

6d5873d7f2 drivers/i2c: Add driver for rt5663 codec
This commit adds a new driver for the RT5663 codec to use instead
of the generic i2c driver.  Since the kernel needs additional
driver-specific device properties we need a BIOS driver that can
provide those properties.

The kernel driver devicetree properties for this codec are at:
linux/Documentation/devicetree/bindings/sound/rt5663.txt

This was tested by booting and verifying the generated SSDT
contains the expected device properties in _DSD.

The function find_fsp() parses the FSP header and returns either a valid

find_fsp() only takes care about a NULL-pointer but not about a possible
error code. This leads to memory access violations in case of error when
FspTempRamInit is called.

To avoid this and to let the user know that there was an error while
parsing the FSP header show an error message and the error code.

2db7922cca siemens/nc_fpga: Modify macro FPGA_SET_PARAM to avoid hwilib errors
The macro FPGA_SET_PARAM was introduced to make the setting of different
FPGA registers with the appropriate values from hwinfo more
transparent. The hwilib takes care about the size of the provided buffer
where the requested value should be stored in. The fields in hwinfo have
not always the same size as the matching registers in the FPGA. So to
avoid errors resulting in a too small buffer when calling hwilib_get_field()
the buffer is now fixed to 32 bit and will be casted to the destination
type when the value is written into the FPGA register.

Changing the field size in hwilib would be the wrong way as the defined
lengths are specified this way to be expandable in the future.

In addition the number of maximum supported temperature sensors is
increased to 8 as the FPGA now supports more.

6e6261e893 rx6110sa: Add a software reset sequence in case of power loss
According to the datasheet the RTC needs a power rising slope of no more
than 100µs/V to ensure a correct power-on reset. If the mainboard that
hosts the RTC cannot guarantee this, a software reset sequence is needed
in the case where the battery was drained completely.

As the rising slope of the power supply depends on so many parameters
and is highly mainboard specific, refactor the initialization code to
perform a software reset every time a power loss event is recognized by
the RTC.

660de34bbf drivers/fsp1_1: decouple VBT from execution of GOP driver
Commit 2e7f6cc introduced the 'no graphics init' option for
FSP 1.1 SoCs using a GOP driver to init the display, but selecting
that option while including a VBT breaks compilation for Braswell
and Skylake devices because the VBT and GOP driver are intertwined.

This patch decouples the VBT from the GOP driver execution,
allowing the 'no graphics init' option to compile (and work)
properly when CONFIG_ADD_VBT_DATA_FILE=y.

If CONSOLE_SPI_FLASH config is enabled, we write the cbmem

log when we read the flash.

This is useful when you don't have usb debugging, and
UART lines are hard to find. Since a failure to boot would
require a hardware flasher anyways, we can get the log
at the same time.

This feature should only be used when no alternative is
found and only when we can't boot the system, because
excessive writes to the flash is not recommended.

This has been tested on purism/librem13 v2 and librem 15 v3 which
run Intel Skylake hardware. It has not been tested on other archs
or with a driver other than the fast_spi.

57cbd21a52 rx6110sa: Add possibility to use both I2C and SMBus for the RTC
The driver for the RTC RX6110SA is designed to be used with I2C bus.
This patch adds the possibility to use SMBus operations to access the
RTC. For this purpose the Kconfig switch RX6110SA_USE_SMBUS is added. It
is not enabled per default so that I2C will be used. One can set this
switch on board level to use SMBus instead.

43314ffae5 uart: Fix bug in {uart8250, uart8250_mem, ns16550}_rx_byte functions
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.

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.)

FSP_PLATFORM_MEMORY_SETTINGS_VERSIONS, which incorproates the SoC

e4d7abc0d4 lib: provide clearer devicetree semantics
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.

eef40eb2a9 drivers/storage: Add SD/MMC/eMMC driver based upon depthcharge
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:

* Replace printf with sd_mmc_error.
* Add sdhc_debug, sdhc_trace and sd_error macros.
* Add Kconfig values to enable storage device debugging and tracing.
* Add tracing and debug support to the SDHCI driver.
* Allow SOC to override more controller features.
* Split out ADMA support.
* Move 1V8 support into SOC routine.
* Move HS400 support into SOC routine.
* Rework clock handling.

* Statically allocate MmcMedia.
* Replace the SdhciHost structure with the MmcCtrlr structure.
* Split the code to support other SD/MMC controllers.
* Split out erase and write support.
* Update the code to be more consistent with the coreboot coding style.
* Only expose calling APIs.
* Divide up mmc.c into 4 modules: MMC, SD, storage card, common code.
* Update debug and error messages.
* Add partition support.
* Display clock frequencies once in MHz.
* Remove mmc_send_cmd, use ctrlr->send_cmd instead.
* Handle error from sd_send_op_cond.
* Allow mainboard to control delays around CMD 0.
* Support command logging.
* Mainboard may set delay after SD/MMC command.
* Display serial number with sd_mmc_trace.
* Remove cmd set parameter from mmc_switch.
* Display errors for timeout and comm errors.

732618975e drivers/i2c/tpm: Remove vendor.irq
The vendor.irq field was originally intended for use as the TPM 1.2
"command complete" interrupt.  However, all actual coreboot tpm drivers
and hardware use the vendor.status method of checking command completion
instead, and this irq field is not used.

Let's just remove this unused functionality to simplify the code.

c4852e7157 drivers/i2c/tpm/cr50: Use tis_plat_irq_status for Cr50 IRQ status
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.

This problem manifests itself as the following build issue when building

tpm2_process_command() returns 0 since that's its current failure

e91d170d21 Remove libverstage as separate library and source file class
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.

8e079000dc nb/i945/gma.c: Refactor panel setup
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.

b94e93531f i2c/generic: Add support for GPIO IRQ
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.

561bebfbaa drivers/intel/gma/vbt: Add Kconfig symbol for SSC ref
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.

71d830fddc i2c/generic: Allow GPIOs to be put in _CRS and PowerResource in ACPI
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
ELAN touchscreen device.

BUG=chrome-os-partner:62311,chrome-os-partner:60194
BRANCH=reef
TEST=Verified that touchscreen works on power-on as well as after
suspend-resume.

This also changes the name of the cbfsfile from "macaddress" to
"rt8168-macaddress" to avoid confusion.

d8e34b2c44 driver/intel/fsp1_1: Fix boot failure for non-verstage case
Currently car_stage_entry is defined only in romstage_after_verstage and
as a result when SEPARATE_VERSTAGE is not selected, there is no
entry point into romstage and romstage will not be started at all.

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
in more appropriate naming convention after this fix.

Tested on SkyLake Saddle Brook (FSP 1.1) and KabyLake Rvp11 (FSP 2.0),
romstage can be started successfully.

a69ac7861b i2c/tpm: Ignore 0xFF bytes for status and burstCount
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.

c2973d196d spi: Get rid of SPI_ATOMIC_SEQUENCING
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.
