When trying to bring up a device with a malfunctioning TPM2 chip, the
driver currently gets stuck waiting for SPI flow control, causing
bricked devices.
This patch puts a 100 ms cap on the waiting time - this should be
enough even for a longest NVRAM save operation which could be under
way on the TPM device.
BRANCH=gru
BUG=chrome-os-partner:59807
TEST=with a matching change in depthcharge, now a gru with corrupted
SPI TPM comes up to the recovery screen (it was not showing signs

Update the mrc cache implementation to use region_file. Instead
of relying on memory-mapped access and pointer arithmetic
use the region_devices and region_file to obtain the latest
data associated with the region. This removes the need for the
nvm wrapper as the region_devices can be used directly. Thus,
the library is more generic and can be extended to work on
different boot mediums.

In the case where the RTC is initialized after the battery is
completely drained the bits for power_mode and cof_selection are set up
with wrongly applied masks.
In the case where the RTC is re-initialized again with no power-loss
after the last initialization the bits for cap_sel, power_mode and
cof_selection are not shifted to the right position.
Both errors lead to a wrong initialization of the RTC and in turn to a
way larger current consumption (instead of 120 nA the RTC current rises
to over 2 µA).
This patch fixes both errors and the current consumption is in the right
range again.
TEST=booted mc_bdx1 and verified current consumption of RTC

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.

2. Try generic flash probing
3. Try spi_flash_programmer_probe with force option
If none of the above steps work, fail probing. Flash controller is
expected to honor force option to decide whether to perform specialized
probing or to defer to generic probing.

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.

1. Re-factor MRC cache driver to properly select RW_MRC_CACHE or
RECOVERY_MRC_CACHE based on the boot mode.
- If normal mode boot, use RW_MRC_CACHE, if available.
- If recovery mode boot:
- Retrain memory if RECOVERY_MRC_CACHE not present, or recovery is
requested explicity with retrain memory request.
- Use RECOVERY_MRC_CACHE otherwise.
2. Protect RW and RECOVERY mrc caches in recovery and non-recovery boot
modes. Check if both are present under one unified region and protect
that region as a whole. Else try protecting individual regions.
3. Update training data in appropriate cache:
- Use RW_MRC_CACHE if normal mode.
- Use RECOVERY_MRC_CACHE if present in recovery mode. Else use
RW_MRC_CACHE.
4. Add proper debug logs to indicate which training data cache is used

1. Export i2c_generic_fill_ssdt to allow other device-specific i2c
drivers to share and re-use the same code for generating AML code for
SSDT. In order to achieve this, following changes are required:
a. Add macro I2C_GENERIC_CONFIG that defines a structure with all
generic i2c device-tree properties. This macro should be placed by the
using driver at the start of its config structure.
b. Accept a callback function to add any device specific information to
SSDT. If generic driver is used directly by a device, callback would be
NULL. Other devices using a separate i2c driver can provide a callback
to add any properties to SSDT.
2. Allow device to provide _CID.

Add a config option to the generic I2C device driver to indicate to
the OS that this device should be probed before being added.
This can be used to provide ACPI device instantiations to devices that
may not actually exist on the board. For example, if multiple trackpad
vendors are supported on the same board they can both be described in
ACPI and the OS will probe the address and load the driver only if the
device responds to the probe at that address.

Originally I thought it would be cleaner to keep this code in one
place, but as things continue to diverge it ends up being easier
to split this into its own driver. This way the different drivers
in coreboot, depthcharge, and the kernel, can all be standalone
and if one is changed it is easier to modify the others.
This change splits out the cr50 driver and brings along the basic
elements from the existing driver with no real change in
functionality. The following commits will modify the code to make
it consistent so it can all be shared with depthcharge and the
linux kernel drivers.

This reverts commit a5e419c51187d24818f056327746a18676fe3a20.
|
|
Support reading the ACPI GPE status (on x86) to determine when
the cr50 is ready to return response data or is done processing
written data. If the interrupt is not defined by Kconfig then
it will continue to use the safe delay.
This was tested with reef hardware and a modified cr50 image
that generates interrupts at the intended points.

Use two different timeouts in the driver. The 2ms timeout is needed
to be safe for cr50 to cover the extended timeout that is seen with
some commands. The other at 2 seconds which is a TPM spec timeout.

Originally I thought it would be cleaner to keep this code in one
place, but as things continue to diverge it ends up being easier
to split this into its own driver. This way the different drivers
in coreboot, depthcharge, and the kernel, can all be standalone
and if one is changed it is easier to modify the others.
This change splits out the cr50 driver and brings along the basic
elements from the existing driver with no real change in
functionality. The following commits will modify the code to make
it consistent so it can all be shared with depthcharge and the
linux kernel drivers.

Remove fsp1.1 driver code that adds vbt.bin & use soc/intel/common
instead to add vbt.bin in cbfs.
Also, VBT blob is added to CBFS as RAW type hence when walking the
CBFS to find vbt.bin, search with type as RAW.

The TPM driver was largely ignoring the meaning of the command
ready bit in the status register, instead just arbitrarily
sending it at the end of every receive transaction.
Instead of doing this have the command ready bit be set at the
start of a transaction, and only clear it at the end of a
transaction if it is still set, in case of failure.
Also the cr50 function to wait for status and burst count was
not waiting the full 2s that the existing driver does so that
value is increased. Also, during the probe routine a delay is
inserted after each status register read to ensure the TPM has
time to actually start up.

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.

If the TPM completely fails to respond then the vendor structure may not
have assigned handlers yet, so catch that case and return error so the
boot can continue to recovery mode instead of asserting over and over.

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
is described properly in the SSDT.

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.

Allow the sleep durations used by the driver to be set by the
specific chip so they can be tuned appropriately.
Since we need to read the chip id to know the values use very
conservative defaults for the first command and then set it
to the current values by default.

Use CAR accessors where needed for accessing static data.
In some cases this required some minor restructuring to pass
in a variable instead of use a global one.
For the tpm_vendor_init the structure no longer has useful
defaults, which nobody was depending on anyway. This now
requires the caller to provide a non-zero address.
Tested by enabling I2C TPM on reef and compiling successfully.
