In order to support wake from D3cold, most devices require extra

In order to support wake from D3cold, most devices require extra
circuitry and possibly out-of-band communications to the host.
Therefore, assume that most SPI peripherals that do have wake
capabilities support wake from D3hot rather than D3cold.
This also allows coreboot to expose a power resource to perform power
sequencing for a SPI peripheral that is intended to retain power in
S3/S0ix.
If support for a device with d3cold wake support is needed, it could be
added in later as an option.

Move elog_internal.h to commonlib/bsd/include/bsd/.
And rename it from elog_internal.h to elog.h.
Since this file will be included from util/ it also converts the "uNN"
types into "uintNN_t" types.
The two defines that are not used by util/ are moved to
drivers/elog/elog.c, the only file that includes them.
Move also the function elog_verify_header() from drivers/elog/, to
commonlib/bsd/elog.c since this function will be called from util/
as well.
The rationale behind moving elog's defines & structs to
commonlib/bsd/include is to make them available to util/ tools and/or
payloads (should it be needed in the future).
The files that are being relicensed to BSD were coded by Duncan Laurie,
and he is Ok with the relicense.

The Fast Read Dual Output and Fast Read Dual I/O commands are
practically identical, the only difference being how the read address is
transferred (saving a whooping 2 bytes which is totally irrelevant for
the amounts of data coreboot tends to read). We originally implemented
Fast Read Dual Output since it's the older command and some older
Winbond chips only supported that one... but it seems that some older
Macronix parts for whatever reason chose to only support Fast Read Dual
I/O instead. So in order to make this work for as many parts as
possible, I guess we'll have to implement both. (Also, the Macronix
device ID situation is utter madness with different chips with different
capabilities often having the same ID, so we basically have to make a
best-effort guess to strike a trade-off between fast speeds and best
chance at supporting all chips. If this turns out to be a problem later,
we may have to add Kconfig overrides for this or resort to SFDP parsing,
although that would defeat the whole point of trying to be fast.)

This reverts commit ce0e2a014009390c4527e064efb59260ef4d3a3b which was
originally introduced as a workaround for the bug that the Linux kernel
doesn't know what to do with type 16 memory region in the e820 table
where CBMEM resides and disallowed accessing it. After depthcharge was
patched to mark the type 16 region as a normal reserved region, the
Linux kernel now can access the BERT region and print BERT errors. When
SeaBIOS was used as payload it already marked the memory region
correctly, so it already worked in that case.
After commit 8c3a8df1021b8a2789c2a285557401837f9fc2b8 that removed the
usage of the BERT memory region reserved by the FSP driver by the AMD
Picasso and Cezanne SoCs and made them use CBMEM for the BERT region,
no other SoC code uses this functionality. The Intel Alderlake and
Tigerlake SoCs put the BERT region in CBMEM and never used this reserved
memory region and the change for the Intel server CPU to use this was
abandoned and never landed in upstream coreboot. AMD Stoneyridge is the
only other SoC/chipset that selects ACPI_BERT, but since it doesn't
select or use the FSP driver, it also won't be affected by this change.
TEST=Behavior of the BERT code doesn't change on Mandolin

Since TBT controller can have maximum 2 ports per controller, our
code will loop over DFP structure twice and determine port number.
Retimer driver used to assign port number as below:
1. Check if power GPIO is assigned for particular DFP entry or not
2. If entry is there, assign loop count as port number
Since loop count is 2, retimer will never assign port number = 2
even if it's present. In case of more than 1 controller, port number
assigned will still be 0 or 1 even though actual port index might
be 2 or 3. This will create an issue where even if you do transaction
on device on controller 2 (port index 2 or 3), EC will route it on
port 0 or 1 due to incorrect port index.
Update the driver flow as per below to handle this scenario:
1. Check if power GPIO is assigned for particular DFP entry or not
2. Get USB port number from config since it's stored in usb port
information under devicetree
3. Pass the port number to ACPI SSDT and EC code
Above changes will ensure that we're assigning correct port
number as per calculation and EC will use correct port index.

Currently the flow for opregion init is as below:
1. Allocate memory for opregion first (cbmem_add(opregion))
2. Check if VBT size > 6 KiB (this requires extended VBT support)
3. In case of extended VBT requirement, we allocate another chunk
of memory which is equal to size of VBT (cbmem_add(extended_vbt))
4. Pass physical address pointer to OS via RVDA
We can optimize the above flow to allocate single chunk of memory by
checking VBT size in earlier step. The new optimized flow for opregion
init is as below:
1. Check if VBT size > 6 KiB (this requires extended VBT support)
2. In case of extended VBT requirement, total memory to be allocated
is calculated as sizeof(opregion) + sizeof (extended_vbt)
In case where VBT size is < 6 KiB, total memory requirement would
be equal to sizeof(opregion)
3. Based on above calculation, allocate single chunk of memory based on
total size.
This will also be helpful for the case of virtualization where guest
users don't have access to physical address and when it needs relative
address of VBT compared to absolute address.
In case of opregion 2.1 spec, we need to pass relative address of
VBT from opregion base in RVDA. This optimization will help in meeting
this requirement since relative address of extended VBT is easy to get.
This change will ensure that it meets opregion specification
requirement and will be compatible with future versions as well.

APIC Serial Bus pins were removed with ICH5 already, so a choice
'irq_on_fsb = 0' would not take effect. The related register BOOT_CONFIG
0x3 is also not documented since ICH5.
For emulation/qemu-q35 with ICH9 the choice INTERRUPT_ON_APIC_BUS was
wrong and ignored as BOOT_CONFIG register emulation was never implemented.
For ICH4 and earlier, the choice to use FSB can be made based on the
installed CPU model but this is now just hardwired to match P4 CPUs of
aopen/dxplplusu.
For sb/intel/i82371eb register BOOT_CONFIG 0x3 is also not defined
and the only possible operation mode there is APIC Serial Bus, which
requires no configuration.

The loads of the FSPM and FSPS binaries are not insignificant amounts of

look like that time is still part of the romstage init time.

This driver was inspired from soc/intel/common/block/pci/rtd3. I decided
to copy and modify it because the Intel driver has a lot of Intel
specific code.
This driver has been stripped down to only provide a power resource and
set the StorageD3Enable property. This driver is SoC agnostic and does
not handle suspending the actual PCIe root port. That should be
implemented by an SoC specific driver.
This is required for Guybrush to suspend/resume properly because the
NVMe power is tied to the S0 power rails, so the kernel needs to place
the device into D3.
BUG=b:184617186

Since the OS provides its own driver for the I2C controller it can
choose to use a bus speed other than the one used at coreboot runtime.
In this case it would be good to provide a way how the needed bus
timings are communicated to the OS, since these are very board-specific
and there is no way that the OS can know them other than read the
appropriate ACPI reported timings.
This patch adds some code to report additional bus speed timings if
there are some defined in the devicetree.

There are cases where the RTC_VRT bit in register D stays set after a
power failure while the real date and time registers can contain rubbish
values (can happen when RTC is not buffered). If we do not detect this
invalid date and/or time here and keep it, Linux will use these bad
values for the initial timekeeper init. This in turn can lead to dates
before 1970 in user land which can break a lot assumptions.
To fix this, check date and time sanity when the RTC is initialized and
reset the values if needed.

In commit b64db833d6 a basic ACPI support was added to the driver.
With this support an SSDT-entry is created for this RTC and it is now
visible to the OS via ACPI. In Linux the PNP-devices, which are
reported over ACPI, are scanned rather early and if the entry is found,
the device is claimed even if there is no driver available yet.
In this case, when the native RTC-driver without ACPI-support is loaded
and tries to register this device, the RTC is already blocked by the
PNP-drivers and cannot be used anymore. This leads to a non-usable RTC
on kernels where the needed ACPI-extension is not yet merged into the
RTC driver.
This patch provides a way to disable the ACPI-support for the RTC if
needed.

we've been using "direct mode", which works by basically making the
bridge I2C device listen to another chip address besides its own and
proxy all requests received there directly to the eDP AUX channel. The
great part about that mode is that it is super easy and hassle-free to
use. The not so great part about it is that it doesn't work: for EDID
extensions, the last byte (which happens to contain the checksum) is
somehow always read as zero. We presume this is a hardware bug in the
bridge part.
The other, much more annoying way is "indirect mode", where each byte
transmitted over the AUX channel has to be manually set up in the I2C
registers of the bridge, just like we're already doing with DPCD
transactions. Thankfully, we can reuse most of the DPCD code for this so
it's not a lot of extra code. It's a bit slower but not as much as you'd
expect (26ms instead of 18ms on my board), and the difference is not
very relevant compared to common total times for display init.
Also, some of the (previously unused) enum definitions for the AUX_CMD
mode field of the bridge had just been plain wrong for some reason, and
needed to be fixed to make this work.

If device is supported as a wake source, _S0W should be set to D3hot.
This ensures that the device is put into D3hot by the OSPM.
Power resource(PRIC) for the device is listed in both _PR0 and _PR3. Thus, it ensures that the OSPM does not turn off power resource when device is put into D0 and D3hot. Hence, it is capable of waking the system from D3hot state. However, if it is put into D3cold, then the power resource is turned off by the OSPM.
The devices we are currently looking at for touchscreen/touchpad

We had the addrspace_32bit rdev in prog_loaders.c for a while to help
represent memory ranges as an rdev, and we've found it useful for a
couple of things that have nothing to do with program loading. This
patch moves the concept straight into commonlib/region.c so it is no
longer anchored in such a weird place, and easier to use in unit tests.
Also expand the concept to the whole address space (there's no real need
to restrict it to 32 bits in 64-bit environments) and introduce an
rdev_chain_mem() helper function to make it a bit easier to use. Replace
some direct uses of struct mem_region_device with this new API where it
seems to make sense.

Traditionally, for each Intel platform using FSP, FSP-S has at some
point configured GPIOs differently than the mainboard configuration in
coreboot. This has resulted in various side-effects in coreboot,
payload and OS because of misconfigured GPIOs. On more recent Intel
platforms, a UPD `GpioOverride` is added that coreboot can use to
ensure that FSP does not touch any GPIO configuration.
This change adds a debug option `CHECK_GPIO_CONFIG_CHANGES` to fsp2_0
driver in coreboot that makes a platform callback `gpio_snapshot` to
snapshot GPIO configuration before making a call to FSP SiliconInit
and Notify phases. This snapshot is then compared against the GPIO
configuration using platform callback `gpio_verify_snapshot` after
returning from FSP. The callbacks are not added to romstage (FSP-M)
because mainboard configures all pads in ramstage.
This debug hook allows developers to dump information about any pads
that have a different configuration after call to FSP in ramstage. It
is useful to identify missed UPD configurations or bugs in FSP that
might not honor the UPDs set by coreboot.
This debug hook expects the platform to implement the callbacks
`gpio_snapshot` and `gpio_verify_snapshot`. These can be implemented
as part of the common GPIO driver for platforms using
FSP2.0+. Platforms that implement this support must select the config
`HAVE_GPIO_SNAPSHOT_VERIFY_SUPPORT` to make the debug config
`CHECK_GPIO_CONFIG_CHANGES` visible to user.
Proposal for the GPIO snapshot/verify support was discussed in the RFC
CB:50829.

if we know that the "device" is always just memory. This patch changes

really wants this to be an rdev, introduce a prog_chain_rdev() helper to

IPMI OEM command set processor information has already been implemented
in u-root payload:
https://github.com/u-root/u-root/commit/efdc3a30ecca53e8b50b863969173969127fa384
Also this command has a higher chance to see BMC KCS timeout issue when
coreboot log level is 4, which can be avoided if this command is run at
a later stage such as LinuxBoot.

Now that SAR support in VPD is deprecated in coreboot, there is no
need for a separate Kconfig `WIFI_SAR_CBFS` as the SAR table is only
supported as a CBFS file. This change drops the config `WIFI_SAR_CBFS`
from drivers/wifi/generic/Kconfig and its selection in
mb/google/.../Kconfig.
wifi_sar_defaults.hex is added to CBFS only if
CONFIG_WIFI_SAR_CBFS_FILEPATH is not empty because current mainboards
do not provide a default SAR file in
coreboot. Thus, CONFIG_WIFI_SAR_CBFS_FILEPATH is updated to have a
default value of "".
