Its spreading copies got out of sync. And as it is not a standard header
but used in commonlib code, it belongs into commonlib. While we are at
it, always include it via GCC's `-include` switch.
Some Windows and BSD quirk handling went into the util copies. We always
guard from redefinitions now to prevent further issues.

There seem to be SPI controllers that don't need the individual
flash chip drivers. For those postcar support was added in b6b1b23
(console/flashconsole: Enable support for postcar). However for
SPI controllers that need the individual drivers (i.e. those with

stage was broken.
For all other stages, the set of compilation units stays the same.

Julius brought up confusion about the current spi api in [1]. In order
alleviate the confusion stemming from supporting x86 spi flash
controllers:
- Remove spi_xfer_two_vectors() which was fusing transactions to
accomodate the limitations of the spi controllers themselves.
- Add spi_flash_vector_helper() for the x86 spi flash controllers to
utilize in validating driver/controller current assumptions.
- Remove the xfer() callback in the x86 spi flash drivers which
will trigger an error as these controllers can't support the api.

Sometimes when bringing up a new board it can take a while until you
have all the peripheral drivers ready. For those cases it is nice to be
able to bitbang certain protocols so that you can already get further in
the boot flow while those drivers are still being worked on. We already
have this support for I2C, but it would be nice to have something for
SPI as well, since without SPI you're not going to boot very far.
This patch adds a couple of helper functions that platforms can use to
implement bit-banging SPI with minimal effort. It also adds a proof of
concept implementation using the RK3399.

The spi_flash_cmd_read_fast() and spi_flash_cmd_read_slow() were just
passing full size buffers to the spi controller ops. However, the
code wasn't honoring what the spi controller can actually perform.
This would cause failures to read on controllers when large requests
were sent in. Fix this by introducing a
spi_flash_cmd_read_array_wrapped() function that calls
spi_flash_cmd_read_array() in a loop once the maximum transfer size is
calculated based on the spi controller's settings.

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.

When Cr50 TPM is being reset, it continues replying to the SPI bus
requests, sends wrong register values in response to read requests.
This patch makes sure that the TPM driver does not proceed unless
proper value is read from the TPM device identification register.

If CONSOLE_SPI_FLASH config is enabled, we write the cbmem
messages to the 'CONSOLE' area in FMAP which allows us to grab the
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.

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.)

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.

Commit 36b81af (spi: Pass pointer to spi_slave structure in
spi_setup_slave) changes the way spi_setup_slave handles the spi_slave
structure. Instead of expecting spi controller drivers to maintain
spi_slave structure in CAR_GLOBAL/data section, caller is expected to
manage the spi_slave structure. This requires that spi_flash drivers
maintain spi_slave structure and flash probe function needs to make a
copy of the passed in spi_slave structure.
This change fixes the regression on Lenovo X230 and other mainboards.

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.

The SPI drivers for the various chipsets are not consistent in
their handling of when they are accessible. Coupled with the
unknown ordering of boot_device_init() being called this can
lead to unexpected behavior (probing failures or hangs). Instead
move the act of initializing the SPI flash boot device to when
the various infrastructure requires its usage when it calls
boot_device_rw(). Those platforms utilizing the RW boot device
would need to ensure their SPI drivers are functional and
ready when the call happens.
This further removes any other systems failing to boot as
reported in https://ticket.coreboot.org/issues/67.

such that the SPI drivers can do any work required prior to performing

callers ensured spi_init() was called before any SPI transactions.

On many x86 platforms the boot device is SPI which is memory
mapped. However, in order to write to the boot device one needs
to use the SPI api. Therefore, provide a common implementation
of boot_device_rw() which has no mmap() functionality. It only
reads, writes, and erases. This will be used in the existing
infrastructure but in a SPI agnostic way.
Two options are added:
1. BOOT_DEVICE_SPI_FLASH_RW_NOMMAP
2. BOOT_DEVICE_SPI_FLASH_RW_NOMMAP_EARLY
The former is auto-selected when COMMON_CBFS_SPI_WRAPPER is not
selected. The latter can be used to include the implementation
in the early stages such as bootblock, verstage, and romstage.

unconditonally regardless if the probe was for the boot device
or even if the boot devcie was flash. Moreover, there's no need
to report the SPI information if the boot device isn't even SPI.
Lastly, it's possible that the boot device is a SPI flash, but
the platform may never probe (selecting SPI_FLASH) for the
actual device connected. In that situation don't fill anything

SPI wrapper. The RW region_device is the same as the read-only
one. As noted in the boot_device_rw() introduction patch the
mmap() support should not be used in conjuction with writing
as that results in incoherent operations. That's fine as the
current mmap() support is only used in the cbfs layer which
does not support writing, i.e. no cbfs regions would be

The SPI_FLASH option is auto-selected if the platform provides

device.
Other platforms may provide similar support, but they do that
in a device specific manner such as selecting SPI_FLASH
explicitly. This provides clearance against build failures
where chipsets don't provide SPI API implementations even
though the platform may use a SPI flash to boot.

specific to SPI flash. As such it should be moved into

it correctly depends on BOOT_DEVICE_SPI_FLASH. Additionally

selecting COMMON_CBFS_SPI_WRAPPER which allows for culling
