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.

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

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.

Almost all boards and chipsets within the codebase assume or
use SPI flash as the boot device. Therefore, provide an option
for the boards/chipsets which don't currently support SPI flash
as the boot device. The default is to assume SPI flash is the
boot device unless otherwise instructed. This falls in line
with the current assumptions, but it also allows one to
differentiate a platform desiring SPI flash support while it not
being the actual boot device.
One thing to note is that while google/daisy does boot with SPI
flash part no SPI API interfaces were ever implemented. Therefore,
mark that board as not having a SPI boot device.

All flash drivers are automatically included in the build unless
COMMON_CBFS_SPI_WRAPPER was selected. However, there are cases
where these drivers are unnecessary such as certain intel platforms
where spi controller uses hardware sequencing without any ability
to manually probe the device. Therefore, provide an option that the

option is still honored by not including all drivers when that

Although we have already support for the flash chip N25Q128 there is a
similar type available which has the same geometry and opcodes but
unfortunately a slightly different device type ID. While the already
supported N25Q128 has the ID 0xbb18 this one has the ID 0xba18.
To make both types available in the flash support table, use N25Q128A as
the flash name. This name can be found in the datasheet which can be
found here:

This introduces a SPI TPM driver compliant with the TCG issued "TPM
Profile (PTP) Specification Revision 00.43" which can be found by
googling its title.
The driver implements both the hardware flow control protocol and the
TPM state machine.
The hardware flow control allows to map SPI based TPM devices to the
LPC address space on x86 platforms, on all other platforms it needs to
be implemented in the driver software.
The tis layer is somewhat superficial, it might have to be expanded
later.
A lot more implementation details can be found in the code comments.
Also, it is worth mentioning that this is not a complete version of
the driver: its robustness needs to be improved, delay loops need to
be bound, error conditions need to propagate up the call stack.

Until now it was assumed that all TPM devices were of the same type
(TCG 1.2 spec compliant) and x86 based boards had LPC connected TPMs
and all other boards had I2C connected TPMs.
With the advent of TPM2 specification there is a need to be able to
configure different combinations of TPM types (TPM or TPM2) and
interfaces (LPC, I2C and SPI).
This patch allows to do it. Picking Chrome OS still assumes that the
board has a TPM device, but adding MAINBOARD_HAS_TPM2 to the board's
Kconfig will trigger including of TPM2 instead.
MAINBOARD_HAS_LPC_TPM forces the interface to be set to LPC, adding
SPI_TPM to the board config switches interface choice to SPI, and if
neither of the two is defined, the interface is assumed to be I2C.
BRANCH=none
BUG=chrome-os-partner:50645
TEST=verified that none of the generated board configurations change
as a result of this patch. With the rest of the stack in place it
is possible to configure different combinations of TPM types and
interfaces for ARM and x86 boards.

The EM100Pro allows the debug console to be sent over the SPI bus.
This is not yet working in romstage due to the use of static variables
in the SPI driver code. It is also not working on chipsets that have
SPI write buffers of less than 10 characters due to the 9 byte
command/header length specified by the EM100 protocol.
While this currently works only with the EM100, it seems like it would
be useful on any logic analyzer with SPI debug - just filter on command
bytes of 0x11.

We've seen an increasing need to reduce stack sizes more and more for
space reasons, and it's always guesswork because no one has a good idea
how little is too litte. We now have boards with 3K and 2K stacks, and
old pieces of common code often allocate large temporary buffers that
would lead to very dangerous and hard to detect bugs when someone
eventually tries to use them on one of those.
This patch tries improve this situation at least a bit by declaring 2K
as the minimum stack size all of coreboot code should work with. It
checks all function frames with -Wstack-usage=1536 to make sure we don't
allocate more than 1.5K in a single buffer. This is of course not a
perfect test, but it should catch the most common situation of declaring
a single, large buffer in some close-to-leaf function (with the
assumption that 0.5K is hopefully enough for all the "normal" functions
above that).
Change one example where we were a bit overzealous and put a 1K buffer
into BSS back to stack allocation, since it actually conforms to this
new assumption and frees up another kilobyte of that highly sought-after
verstage space. Not touching x86 with any of this since it's lack of
__PRE_RAM__ BSS often requires it to allocate way more on the stack than
would usually be considered sane.

A new CBFS API is introduced to allow making CBFS access
easier for providing multiple CBFS sources. That is achieved
by decoupling the cbfs source from a CBFS file. A CBFS
source is described by a descriptor. It contains the necessary
properties for walking a CBFS to locate a file. The CBFS
file is then decoupled from the CBFS descriptor in that it's
no longer needed to access the contents of the file.
All of this is accomplished using the regions infrastructure
by repsenting CBFS sources and files as region_devices. Because
region_devices can be chained together forming subregions this
allows one to decouple a CBFS source from a file. This also allows
one to provide CBFS files that came from other sources for
payload and/or stage loading.
The program loading takes advantage of those very properties
by allowing multiple sources for locating a program. Because of
this we can reduce the overhead of loading programs because
it's all done in the common code paths. Only locating the
program is per source.

As per discussion with lawyers[tm], it's not a good idea to
shorten the license header too much - not for legal reasons
but because there are tools that look for them, and giving
them a standard pattern simplifies things.
However, we got confirmation that we don't have to update
every file ever added to coreboot whenever the FSF gets a
new lease, but can drop the address instead.
util/kconfig is excluded because that's imported code that
we may want to synchronize every now and then.

A payload may want to run erase operations on SPI NOR flash without
re-probing the device to get its properties. This patch passes up
three properties of flash to achieve that:
- The size of the flash device
- The sector size, i.e., the granularity of erase
- The command used for erase
The patch sends the parameters through coreboot and then libpayload.
The patch also includes a minor refactoring of the flash erase code.
Parameters are sent up for just one flash device. If multiple SPI
flash devices are probed, the second one will "win" and its
parameters will be sent up to the payload.
TEST=Observed parameters to be passed up to depthcharge through
libpayload and be used to correctly initialize flash and do an erase.
TEST=Winbond and Gigadevices spi flash drivers compile with the changes;
others don't, for seemingly unrelated reasons.

Some SPI controllers (like Imgtec Pistachio), have a hard limit on SPI
read and write transactions. Limiting transfer size in the wrapper
allows to provide the API user with unlimited transfer size
transactions.
The tranfer size limitation is added to the spi_slave structure, which
is set up by the controller driver. The value of zero in this field
means 'unlimited transfer size'. It will work with existion drivers,
as they all either keep structures in the bss segment, or initialize
them to all zeros.
This patch addresses the problem for reads only, as coreboot is not
expected to require to write long chunks into SPI devices.

Coreboot has all necessary infrastructure to use the proper SPI flash
interface in bootblock for CBFS. This patch creates a common CBFS
wrapper which can be enabled on different platforms as required.
COMMON_CBFS_SPI_WRAPPER, a new configuration option, enables the
common CBFS interface and prevents default inclusion of all SPI chip
drivers, only explicitly configured ones will be included when the new
feature is enabled. Since the wrapper uses the same driver at all
stages, enabling the new feature will also make it necessary to
include the SPI chip drivers in bootblock and romstage images.
init_default_cbfs_media() can now be common for different platforms,
and as such is defined in the library.

This consolidates all calls to spi_claim_bus() and spi_release_bus()
to a single location where spi_xfer() is called. This avoids confusing
(and potentially redundant) calls that were being done throughout the
generic spi_flash.c functions and chip-specific functions.
I don't think the current approach could even work since many chip
drivers assert /CS once and then issue multiple commands such as page
program followed by reading the status register. I suspect the reason
we didn't notice it on x86 is because the ICH/PCH handled each
individual command correctly (spi_claim_bus() and spi_release_bus()
are noops) in spite of the broken code.

This adds a wrapper function and a Kconfig variable to differentiate
between SPI controllers which use atomic cycle sequencing versus
those where the transaction sequence is controlled manually. Currently
this boils down to x86 vs. non-x86.
Yes, it's hideous. The current API only worked because, for better or
worse, x86 platforms have been homogeneous in this regard since they
started using SPI as an alternative to FWH for boot flash. Now that
we have non-x86 platforms which use general purpose SPI controllers,
we should overhaul the entire SPI infrastructure to be more adaptable.

Depending on the platform the underlying regions vboot requires
may not be accessible through a memory-mapped interface. Allow
for non-memory-mapped regions by providing a region request
abstraction. There is then only a few touch points in the code to
provide compile-time decision making no how to obtain a region.
For the vblocks a temporary area is allocated from cbmem. They
are then read from the SPI into the temporarily buffer.

Support added for Micron N25Q128 SPI flash, which has
the same manufacturer id as ST Micro. Jedec ID =
0x20 0xBB 0x18. Since existing stmicro.c only compares
the last device id byte, this flash is mistakenly
identified as M25P128, which has ID = 0x20 0x20 0x18.
To handle this situation and avoid breaking code for
existing devices, a two byte .id member is added.
New devices should be added to the beginning of the
flash table array with .idcode = STM_ID_USE_ALT_ID and
.id = the two byte jedec device id.
A 4KB subsector erase capability is added and used for
this new device. It requires using a different SPI
op-code supported by adding .op_erase member. Previous
devices defined in stmicro.c are assigned their original
op-code for 64KB sector erase.
N25Q128 is now working on a custom designed Bayley Bay
based board. Tested by verifying the MRC fastboot cache
is successfully (re)written. Note that previous devices
were not retested.

tegra124: implement x2 mode for SPI transfers on CBFS media
This implements x2 mode when reading CBFS media over SPI.
In theory this effectively doubles our throughput, though the initial
results were almost negligibly better. Using a logic analyzer we see
a pattern of 12 clocks, ~70ns delay, 4 clocks, ~310ns delay. So if we
want to see further gains here then we'll probably need to tune AHB
arbitration and utilization to eliminate bubbles/stalls when copying
from APB DMA.

There are two separate restrictions to take into account:
Page Program command must not cross address boundaries defined by the
flash part's page size.
Total number of bytes for any command sent to flash part is restricted
by the SPI controller capabilities.
Consider
CONTROLLER_PAGE_LIMIT=64, page_size=256, offset=62, len=4.
This write would be split at offset 64 for no reason.
Consider
CONTROLLER_PAGE_LIMIT=40, page_size=256, offset=254, len=4.
This write would not be split at page boundary as required.
We do not really hit the second case. Nevertheless, CONTROLLER_PAGE_LIMIT
is a misnomer for the maximum payload length supported by the SPI controller
and is removed in a followup.

Whenever spi_xfer is called and whenver it's implemented, the natural unit for
the amount of data being transfered is bytes. The API expected things to be
expressed in bits, however, which led to a lot of multiplying and dividing by
eight, and checkes to make sure things were multiples of eight. All of that
can now be removed.

At the end of some SPI operations the SPI device needs to be polled
to determine if it is done with the operation. For SPI data writes
the predicted time of that operation could be less than 10us.
The current per loop delay of 500us is adding too much delay.
This change replaces the delay(x) in the do-while loop with a
timer so that the actual timeout value won't be lengthened by the
delay of reading the SPI device.

Adds support for the following Adesto Technologies
SPI Flash parts.
AT25DF081
AT25DF321
AT25DF641
It has been tested on an Orion VPX7654 board populated
with an AT25DF321A part. The "08" and "64" densities have not
been tested.
These parts are the successors of the Atmel AT26DF line that
was spun out or purchased by Adesto.
In this patch, adesto.c is identical to winbond.c with part
entries for the Adesto parts. The datasheet for the AT25DF parts
includes a "100MHz" programming command in addition to the "85MHz"
command that is currently used but this patch does not add support
for that enhanced programming mode.
