689a950047 UPSTREAM: drivers/i2c/tpm: Fix early TPM probe
The early TPM probe was done directly in tis.c ignoring the lower
layer that provides appropriate access to the chip.  Move this into
a tpm_vendor_probe() function so it can use iic_tpm_read() with all
of the built-in delays and semantics instead of calling i2c_readb()
directly from the wrong layer.

This fixes early init failures that were seen with the cr50 i2c tpm
on the reef mainboard.

ea2c258a2e UPSTREAM: drivers/i2c/tpm: Add support for generating ACPI table
Add code to generate an ACPI descriptor for an I2C TPM based
on the device as described in devicetree.cb.

This currently requires the devicetree to provide the HID,
since we don't currently talk to the TPM in ramstage and I
didn't want to add yet another init path for it here.

This was tested on a reef board to ensure that the device

780f007a43 UPSTREAM: drivers/i2c/tpm: Add support for cr50 TPM
Add support for the cr50 TPM used in apollolake chromebooks.
This requires custom handling due to chip limitations, which
may be revisited but are needed to get things working today.

- timeouts need to be longer
- must use the older style write+wait+read read protocol
- all 4 bytes of status register must be read at once
- same limitation applies when reading burst count from status reg
- burst count max is 63 bytes, and burst count behaves
slightly differently than other I2C TPMs
- TPM expects the host to drain the full burst count (63 bytes)
from the FIFO on a read

Luckily the existing driver provides most abstraction needed to
make this work seamlessly.  To maximize code re-use the support
for cr50 is added directly instead of as a separate driver and the
style is kept similar to the rest of the driver code.

This was tested with the cr50 TPM on a reef board with vboot
use of TPM for secdata storage and factory initialization.

d13c2fe89b UPSTREAM: vboot: consolidate google_chromeec_early_init() calls
On x86 platforms, google_chromeec_early_init() is used to put the EC
into RO mode when there's a recovery request. This is to avoid training
memory multiple times when the recovery request is through an EC host
event while the EC is running RW code. Under that condition the EC will
be reset (along with the rest of the system) when the kernel verification
happens. This leads to an execessively long recovery path because of the
double reboot performing full memory training each time.

By putting this logic into the verstage program this reduces the
bootblock size on the skylake boards. Additionally, this provides the
the correct logic for all future boards since it's not tied to FSP
nor the mainboard itself. Lastly, this double memory training protection
works only for platforms which verify starting from bootblock. The
platforms which don't start verifying until after romstage need to
have their own calls (such as haswell and baytrail).

e668fdeaba UPSTREAM: drivers/spi: remove unconditional RW boot device initialization
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.

It's necessary to call spi_init() prior to calling spi_flash_probe()
such that the SPI drivers can do any work required prior to performing

such situations, however the SPI API implementations seem to assume the
callers ensured spi_init() was called before any SPI transactions.

This fixes systems that failed to boot introduced by [1]. Issue tracked

3dc99c74ed UPSTREAM: drivers/spi: provide optional implementation of boot_device_rw()
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.

914234f787 UPSTREAM: drivers/spi: ensure SPI flash is boot device for coreboot tables
The spi_flash_probe() routine was setting a global varible
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
in as no correct information is known.

197da15511 UPSTREAM: lib/cbfs_spi: provide boot_device_rw() support
Provide the RW boot device operations for the common cbfs
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
written to with any previous or outstanding mmap() calls.

ef4d5ed57a UPSTREAM: Kconfig: introduce writable boot device notion
Indicate to the build system that a platform provides support
for a writable boot device. The following will provide the
necessary support:

COMMON_CBFS_SPI_WRAPPER users
soc/intel/apollolake
soc/intel/baytrail
soc/intel/braswell
soc/intel/broadwell
soc/intel/skylake

The SPI_FLASH option is auto-selected if the platform provides
write supoprt for the boot device and SPI flash is the boot
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.

e6076f88ab UPSTREAM: drivers/spi: move cbfs_spi.c location
The common boot device spi implementation is very much
specific to SPI flash. As such it should be moved into
that subdirectory. It's still a high-level option but
it correctly depends on BOOT_DEVICE_SPI_FLASH. Additionally
that allows the auto-selection of SPI_FLASH by a platform
selecting COMMON_CBFS_SPI_WRAPPER which allows for culling
of SPI_FLASH selections everywhere.

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.

Commit 0d9cd92e (chromeos: Clean up elog handling) removed the
individual elog_init() calls from mainboards that did them and automated
adding certain events through the boot state machine. Unfortunately,
the new code would sometimes not log any specific event at all, and
thereby also never call elog_init() (through elog_add_event()) which
adds the "System boot" event.

We can assume that any board that configures the eventlog at all
actually wants to use it, so let's just add another call to elog_init()
to the boot state machine so we can ensure it gets called at least once.

c43d0c469c UPSTREAM: drivers/elog: use region_device for mirroring into ram
A region_device can be used to represent the in-memory mirror
of the event log. The region_device infrastructure has builtin
bounds checking so there's no need to duplicate that. In addition,
it allows for removing much of the math juggling for the buffer
size, etc.

ced51977da UPSTREAM: drivers/elog: use offsets for checking cleared buffers
There's only 2 users of checking if the event buffer is cleared
to the EOL value. Each were passing pointers of the in-memory
mirror while also doing calculations for the size to check. Since
the in-memory mirror is one big buffer the only thing required
to know is the offset to start checking from. The check is always
done through the end of the buffer.

9881de61c5 UPSTREAM: drivers/elog: perform writes in terms of offsets
Instead of taking pointers and back-calculating the
proper offset perform writes in terms of the offsets
within the elog region in flash.
