There are MSRs that are programmable per-core not per-thread, so add
a function to check whether current executing CPU is a primary core
or a "hyperthreaded"/secondary core. For instance when trying to
program Core PRMRR MSRs(per-core) with mp_init, cpu exception is thrown
from the secondary thread. This function was used to avoid that.
Potentially this function can be put to common code or arch/x86 or cpu/x86.

Some variants need the internal pull resistor on GPIO_SSUS_40
set explicitly to pull down rather than disabling the pull,
in order for the ram-id to be read correctly via GPIO.
Correct this by adding a function to enable and set the internal pull

Baytrail SoC has a bug where in some cases the DisplayPort can hang
leading to a non-working display (it just stays black). To avoid this
hang, a patch was introduced in 02/2016
(1c3b1112fa - fsp_baytrail: Fix a possible hanging DisplayPort)
but per default not switched on so that each
mainboard can decide if it wants to use this patch or not.
Recently a new case of this bug was reported by Benoit Sansoni
(benoit.sansoni@kontron.com) and he requested to enable this fix per
default as it costs him a lot of time to find the cause and even the
already available fix in coreboot. To avoid this effort for someone
else in the future we can enable this fix per default as no negative
side effects are known and it is now tested at Siemens and at
Kontron on different mainboards with success.
As the goal is to enable this code permanently the config switch is not
longer needed and is removed.

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.

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

Legacy PME are enabled by default in FSP UPD region.
When Legacy PME is enabled, then an SCI is generated and should be
handled by OS and BIOS/Coreboot in collboration. OS requires some
ACPI methods (eg _L69) which help to determine the wake source and also
to clear some registers. But this infrastructure is not present as of
now in coreboot and also linux handles PMEs natively.
Hence the SCI was never handled by OS and the status bits were never
cleared i.e., PCI_EXP_STS.
For this reason the level triggered SCI will remain active and the
system will wake up as soon as it enters S3.
To fix this, diabled Legacy PME (PmSci for Root ports).

1. Try spi_flash_programmer_probe without force option
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

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.

reshuffle all our PLL settings at the last minute. The new settings
match exactly what the Linux kernel expects on boot, so it doesn't need
to reinitialize anything and risk a glitch.
Naturally, changing PLL rates will affect child clocks, so this patch
changes vop_aclk (192MHz -> 200MHz, 400MHz in the kernel), pmu_pclk

similar structures for providing settings for the i2c speed
control. Introduce a new struct lpss_i2c_bus_config and
utilize it in both apollolake and skylake thereby removing
the need for SoC-specific structres. The new structure is
used for initializing a bus fully as the lpss i2c API is
simplified in that lpss_i2c_init() is only required to be
called. The struct lpss_i2c_bus_config structure is passed
in for both initializing and filling in the SSDT information.
The formerly exposed functions are made static to reduce the

1. Update write leveling value to 0x200.
When the wrdqs slave delay is changed to 0x200, the phase between the
dqs and the clock is 0 degrees. The pcb layout can make sure the tDQSS
timing is smaller than 0.25tck, so this value is useful for both higher
and lower frequencies.
2. Disable read leveling for LPDDR3.
The read leveling result is unreliable - the value is not in the middle

As per ME BWG, there are two mechanism to generate a Global
Reset (resets both host and Intel ME), one is through CF9h
IO write of 6h or Eh with "CF9h Global Reset" (CF9GR) bit set,
PMC PCI offset ACh[20]. Another is to issue the Global Reset
MEI message. Because any attempts to cause global reset without
synchronizing the two sides might cause unwanted side effects,
such as unwritten flash data that will get destroyed if the
host were to cause a global reset without informing Intel ME
firmware, the recommended method is to send a Global Reset MEI
message when the following conditions are met:
The PCH chipset firmware just needs to complete the Intel ME
Interface #1 initialization and check the Intel ME HFSTS state
if Intel ME is not in ERROR state and is accepting MEI commands

With a SPI clock above about 24MHz the APB cannot keep up when doing
individual byte transfers. Adjust the driver to use 16-bit reads when
it can, to remove this bottleneck.
Any transaction which involves writing bytes still uses 8-bit transfers,
to simplify the code. These are the transfers that are not time-critical
since they tend to be small. The case that really matters is reading from
SPI flash.
In general we can use 16-bit reads anytime we are transferring an even
number of bytes. If the code detects an odd number of bytes, it tries to
perform the operation in two steps: once in 16-bit mode with an even
number of bytes, and once in 8-bit mode for the final byte. This allow
us to use 16-bit reads even if asked to transfer (for example) 0xf423
bytes.
The limit on in_now and out_now is adjusted to 0xfffe to avoid an extra
transfer when transferring ~>=64KB.

'0x'. If the default value isn't set this way, Kconfig will add the
0x to the start, and the entry can be added unnecessarily to the
defconfig since it's "different" than what was set by the default.
A check for this has been added to the Kconfig lint tool.

The SPI driver is quite slow at reading data. For example, with a 24MHz
clock on gru it achieves a read speed of only 13.9Mbps.
We can correct this by reading the status registers once, then reading as
many bytes as are available before checking the status registers again. It
seems likely that a status register read requires synchronizing with the
SPI FIFO clock domain, which takes a while.

This change modifies the lpss_i2c driver to behave more like
the Linux kernel driver. In particular the controller is only
enabled when processing a transaction, and is disabled after.
This means that errors in one transaction will not affect later
transactions.
Also when disabling the controller the code is supposed to wait
on the enable bit in the "enable status" register and not in
the enable control register. In order to get access to this
register the reg map was expanded to include all registers.
This was tested with the cr50 TPM driver to ensure that if a
transaction does fail that it can be successfully retried instead
of the bus being unusable.

What I suppose this debug code should do is to print the used register
address within the SPI controller while any parts of this address that
belongs to the SPI base address should be omitted. To fix that remove
the subtraction of 0xf020 and adjust the address mask to 0x3ff so that
only the offset to the registers inside the SPI controller will be
visible in the debug messages.
In addition switch to uint8_t and friends over u8 to sync up with used

2. Change the address mask from 0xffff to 0x3ff and remove the subtraction
of the constant value 0xf020 in order to print only the register

3. Switch to uint8_t and friends instead of u8 to sync up with other

This also means we decide to drop the ES1 because it may fail to

Currently boards based on fsp_broadwell_de fail to compile if the config
switch CONFIG_DEBUG_SPI_FLASH is selected. The error is caused by the
usage of const for the address pointer in the functions writeb_, writew_
and writel_. The reason why it stayed hidden for so long is the fact that
the switch is used with the preprocessor and nobody really selects it
until there is a bug one want to find in this area.
This patch fixes the parameter type definition which solves the error.
In addition the config switch is not used on preprocessor level anymore
but instead on compiler level. This ensures that at least the code
syntax is checked on build time even if the config option is not
selected. Also prefix the messages with "SPI:" to make them more
meaningful in a full log.

DCACHE_RAM_SIZE_TOTAL is set to 0x40000 and is being used to
set up CAR. Whereas DCACHE_RAM_SIZE which is set to 0x10000
is used to calculate the _car_region_end in car.ld. If the FSP CAR
requirement is greater than or even close to DCACHE_RAM_SIZE then,
the CAR region for FSP will be determined to be below the overall
CAR region boundary i.e, out of CAR memory range.
This is working with FSP 1.1 because we provide the FspCarSize
and FspCarBase explicitly in a UPD. Hence, FSP is still able to
use the upper region of CAR memory for its purpose.
However, it will be a problem in case of FSP2.0 where FSP usable CAR
is calculated using _car_region_end.
So, Remove the the use of DCACHE_RAM_SIZE_TOTAL and set
DCACHE_RAM_SIZE to correct value i.e, 0x40000(256KB)

Prepare Skylake for FSP2.0 support.
We do not use FSP-T in FSP2.0 driver, hence guard the
FspTempRamInit call under a switch.
In addition to the current early PCH configuration
program few more register, so all in all we do the following,
* Program and enable ACPI Base.
* Program and enable PWRM Base.
* Program TCO Base.
* Program Interrupt configuration registers.
* Program LPC IO decode range.
* Program SMBUS Base address and enable it.
* Enable upper 128 bytes of CMOS.
And split the above programming into into smaller functions.
Also, as part of bootblock_pch_early_init we enable decoding
for HPET range. This is needed for FspMemoryInit to store and
retrieve a global data pointer.
And also move P2SB related definitions to a new header file.

The Rockchip RK3399 integrates a USB Type-C PHY in charge of things like
SuperSpeed line muxing for rotated cable orientations in the SoC. While
fancy, this is very complicated and we don't want to implement support
for the whole thing in firmware. The USB Type-C standard has
intentionally been designed in a way that the USB 2.0 (HighSpeed) lines
always "just work" in any orientation (by just shorting different pins
in the connector together) so that simple use cases like ours can get
basic USB functionality without much hassle.
However, a semi-configured Type-C PHY can confuse USB 3.0 capable
devices into thinking we're actually supporting SuperSpeed, and fail at
that rather than establishing a reliable HighSpeed connection. This
patch sets enough bits in the Type-C PHY to electrically isolate the
SuperSpeed lines from the connector so that the connected device isn't
going to get any fancy ideas and reliably falls back to USB 2.0.
Also clean up the rest of the USB code while we're at it: avoid writing
a few bits that are already in the right state from their reset values
anyway, or reading values whose content we already know for this SoC.
Rename the USB controllers to the name actually used in the Rockchip
documentation (USB OTGx) rather than the name blindly copied from
Exynos code (USB DRDx).

Wake status is calculated from the four pairs of gpe0 in
cbmem CBMEM_ID_POWER_STATE which is filled very early
in romstage and depends on the routing information in
PMC GPE_CFG register. Coreboot sets the proper value
of routing based on devicetree from pmc_init. But when
system goes to S3 on waking up PMC is writing default
values again in GPE_CFG which results in returning
wrong wake status in _SWS. This patch corrects that
behaviour by correcting the gpe0 pairs in cbmem after
PMC sets the routing table in resume path.

ASL files are now in src/soc/intel/common so that
they can be reused but different soc can have different values
e.g., for skylake cpu soc thermal reporting device is at
Bus 0, Device 4, Function 0 while for apollolake it is Bus 0, Device 0,
Function 1. This patch adds a dptf asl file in soc directory where we
can define all values which can change across soc's and can be

When DA_LVDSTX_PWR_ON is not set, LVSH has no power and LVDS DRV
termination status is unknown (floating). This creates a chance that
MIPI output would be influenced. The DSI's LP signal will be half

When DA_LVDSTX_PWR_ON is set, LVSH and LVDS DRV termination are
effective and termination is fixed OFF. The DSI won't be influenced.
We only need to set this register once, so we set it here to prevent
repeatedly setting in the kernel when the system goes to recovery mode.

events, but there's a polarity inversion setting for each IRQ such
that it can pass the signal on to the APIC according to the
expected APIC redirection entry values. This support is needed
in order for the platform/board to set the expected interrupt
polarity into the APIC for gpio signals.

Internally, apollolake routes its interrupts as active high.
This includes SCI, SMI, and ACPI. Therefore, provide helper
macros such that the user can describe an interrupt's active
high/low polarity more easily. It helps for readability when
one is comparing gpio configuration next to APIC configuration
in different files. Additionally, the gpio APIC macros always
use a LEVEL trigger in order to let the APIC handle the
filtering of the IRQ on its own end.
