ce34596f74 device: Add fixed_mem_range_flags() and helpers
Unlike fixed_mem_resource_kb() the arguments are not in KiB.
This allows coccinelle script to assign the base and size
without applying the KiB division or 10 bit right-shift.

Unlike with fixed_mem_resource_kb() the IORESOURCE_STORED flag is
passed in the flags parameter until some inconsistencies in the tree
get resolved.

ee849ba625 dev/i2c_bus: Add declaration, implementation of i2c_dev_detect()
This patch adds the I2C equivalent of an SMBus quick write to an I2C
device, which is used by some I2C drivers as a way to probe the
existence (or absence) of a certain device on the bus, based on
whether or not a 0-byte write to an I2C address is ACKed or NACKed.

i2c_dev_detect() is implemented using the existing i2c bus ops transfer()
function, so no further work is needed for existing controller drivers
to utilize this functionality.

19baa9d51e i2c: Add configurable I2C transfer timeout
This patch introduces CONFIG_I2C_TRANSFER_TIMEOUT_US,
which controls how long to wait for an I2C devices to
produce/accept all the data bytes in a single transfer.
(The device can delay transfer by stretching the clock of
the ack bit.)

The default value of this new setting is 500ms.  Existing
code had timeouts anywhere from tens of milliseconds to a
full second beween various drivers.  Drivers can still have
their own shorter timeouts for setup/communication with the
I2C host controller (as opposed to transactions with I2C
devices on the bus.)

In general, the timeout is not meant to be reached except in
situations where there is already serious problem with the
boot, and serves to make sure that some useful diagnostic
output is produced on the console.

f514b8ae82 device/pci_device: Fix PCIe bridge detection
PCI bus 0 is not below any PCI device. In case of pci_domain_scan_bus(),
it's our virtual `domain` device.

Expecting a PCI device above bus 0 resulted in undefined behavior for

like a PCIe bridge showed issues, though (e.g. OCP/DeltaLake).

8c93feda7f device: Add support for PCIe Resizable BARs
Section 7.8.6 of the PCIe spec (rev 4) indicates that some devices can
indicates support for "Resizable BARs" via a PCIe extended capability.

When support this capability is indicated by the device, the size of
each BAR is determined in a different way than the normal "moving
bits" method. Instead, a pair of capability and control registers is
allocated in config space for each BAR, which can be used to both
indicate the different sizes the device is capable of supporting for
the BAR (powers-of-2 number of bits from 20 [1 MiB] to 63 [8 EiB]), and
to also inform the device of the size that the allocator actually
reserved for the MMIO range.

This patch adds a Kconfig for a mainboard to select if it knows that it
will have a device that requires this support during PCI enumeration.
If so, there is a corresponding Kconfig to indicate the maximum number
of bits of address space to hand out to devices this way (again, limited
by what devices can support and each individual system may want to
support, but just like above, this number can range from 20 to 63) If
the device can support more bits than this Kconfig, the resource request
is truncated to the number indicated by this Kconfig.

BUG=b:214443809

3d121ae1a1 device: Add pciexp_find_next_extended_cap function
Some PCIe devices have extended capability lists that contain

function similar to pciexp_find_extended_cap that can be used to
search through multiple instances of the same capability by returning
the offset of the next extended capability of the given type following
the passed-in offset. The base functionality of searching for a given
capability from an offset is extracted to a local helper function and
both pciexp_find_extended_cap and pciexp_find_next_extended_cap use
this helper.

it is no longer necessary to explicitly add "ERROR: " in front of every

This patch was created by running

  find src/ -type f -exec perl -0777 -pi -e 's/printk\(\s*BIOS_ERR,\s*"ERROR: /printk\(BIOS_ERR, "/gi' '{}' ';'

and doing some cursory review/cleanup on the result. Then doing the same
thing for BIOS_WARN with

  's/printk\(\s*BIOS_WARNING,\s*"WARN(ING)?: /printk\(BIOS_WARNING, "/gi'

Only scan one device if it's a PCIe downstream port.

A PCIe downstream port normally leads to a link with only device 0 on

6de8b42482 arch/x86: Refactor the SMBIOS type 17 write function
List of changes:
1. Create Module Type macros as per Memory Type
(i.e. DDR2/DDR3/DDR4/DDR5/LPDDR4/LPDDR5) and fix compilation
issue due to renaming of existing macros due to scoping the Memory
Type.
2. Use dedicated Memory Type and Module type for `Form Factor`
and `TypeDetail` conversion using `get_spd_info()` function.
3. Create a new API (convert_form_factor_to_module_type()) for
`Form Factor` to 'Module type' conversion as per `Memory Type`.
4. Add new argument as `Memory Type` to
smbios_form_factor_to_spd_mod_type() so that it can internally
call convert_form_factor_to_module_type() for `Module Type`
conversion.
5. Update `test_smbios_form_factor_to_spd_mod_type()` to
accommodate different memory types.
6. Skip fixed module type to form factor conversion using DDR2 SPD4
specification (inside dimm_info_fill()).

Refer to datasheet SPD4.1.2.M-1 for LPDDRx and SPD4.1.2.L-3 for DDRx.

e78fd115e6 qualcomm/sc7180: Switch to common MIPI panel library
This patch changes the sc7180 boards to use the new common MIPI panel
framework, which allows more flexible initialization command packing and
sharing panel definitions between boards. (I'm taking the lane count
control back out again for now, since it seems we only ever want 4 for
now anyway, and if we ever have a need for a different lane count it's
not clear whether that should be a property of the board or the panel or
both. Better to leave that decision until we have a real use case.)

Also, the code was not written to deal with DCS commands that were not a
length divisible by 4 (it would read over the end of the command
buffer). The corresponding kernel driver seems to pad the command with
0xff instead, let's do the same here. (Also increase the maximum allowed
command length to 256 bytes, as per Qualcomm's recommendation.)

b2a1480191 device: Move MIPI panel library from mainboard/google/kukui into common
All boards that are trying to use MIPI panels eventually run into the
problem that they need to store physical parameters and a list of DCS
initialization commands for each panel, and these commands can be very
different (e.g. a large amount of very short commands, a few very large
commands, etc.). Finding a data format to fit all these different cases
efficiently into the same structures keeps being a challenge, and the
Kukui mainboard already once put a lot of effort into designing a
clean, flexible and efficient solution for this. This patch moves that
framework into a common src/device/mipi/ library where it can be used by
other boards as well. (Also, this will hopefully allow us to save some
duplicated work when using the same panel on different boards at some
point.)

7f6ae79280 device: Consider fw_config probing in is_dev_enabled()
With the introduction of fw_config support in coreboot, it is possible
for mainboards to control the state of a device (on/off) in ramstage
using fw_config probe conditions. However, the device tree in
immutable in all other stages and hence `is_dev_enabled()` does not
really reflect the true state as in ramstage.

This change adds a call to `fw_config_probe_dev()` in
`is_dev_enabled()` when device tree is immutable (by checking
DEVTREE_EARLY) to first check if device is disabled because of device
probe conditions. If so, then it reports device as being
disabled. Else, dev->enabled is used to report the device state.

This allows early stages (bootblock, romstage) to use
`is_dev_enabled()` to get the true state of the device by taking probe
conditions into account and eliminates the need for each caller to
perform their own separate probing.

fa1befcb57 device/azalia_device.c: Unify wait_for_valid timeouts
The timeout is never reached when the codec is functioning properly.
Using a small timeout value can result in spurious errors with some
codecs, e.g. a codec that is slow to respond but operates correctly.
When a codec is non-operative, the timeout is only reached once per
verb table, thus the impact on booting time is relatively small. So,
use a reasonably long enough timeout to cover all possible cases.

Remove the unconditional 25 µs delay and increase the timeout delay.
The new value of 1 ms is the maximum of all existing implementations.
Currently, the only boards using this code are AMD reference boards:
- AMD Bilby
- AMD Mandolin
- AMD Padmelon

968ef75988 pciexp_device: Rewrite LTR configuration
I was bugged by spurious "Failed to enable LTR" messages for years.
Looking at the the current algorithm, it is flawed in multiple ways:

* It looks like the author didn't know they implemented a
  recursive algorithm (pciexp_enable_ltr()) inside another
  recursive algorithm (pciexp_scan_bridge()). Thus, at every
  tree level, everything is run again for the whole sub-
  tree.

* LTR is enabled no matter if `.set_ltr_max_latencies` is
  implemented or not. Leaving the endpoints' LTR settings
  at 0: They are told to always report zero tolerance.
  In theory, depending on the root-complex implementation,
  this may result in higher power consumption than without
  LTR messages.

* `.set_ltr_max_latencies` is only considered for the direct
  parent of a device. Thus, even with it implemented, an
  endpoint below a (non-root) bridge may suffer from the 0
  settings as described above.

* Due to the double-recursive nature, LTR is enabled starting
  with the endpoints, then moving up the tree, while the PCIe
  spec tells us to do it in the exact opposite order.

With the current implementation of pciexp_scan_bridge(), it is
hard to hook anything in that runs for each device from top to
bottom. So the proposed solution still adds some redundancy:

First, for every device that uses pciexp_scan_bus(), we enable
LTR if possible (see below). Then, when returning from the bus-
scanning recursion, we enable LTR for every device and configure
the maximum latencies (if supported). The latter runs again on
all bridges, because it's hard to know if pciexp_scan_bus() was
used for them.

When to enable LTR:

* For all devices that implement `.set_ltr_max_latencies`.
* For all devices below a bridge that has it enabled already.

0f30063abf soc/intel/broadwell: Conditionally skip PRE_GRAPHICS_DELAY
It was commented that the need for the delay was mainly related
to external displays and only with VBIOS execution. Move the
delay such that it is done only when we actually need to execute
the VBIOS aka option rom.

A delay is currently only defined for librem/purism_bdw in
its Kconfig. As the description of the issue sounds like it
would equally happen on other platforms when VBIOS is involved,
promote the Kconfig visible option to global scope.

Platform can now select VGA_ROM_RUN_DEFAULT Kconfig to perform graphics
initialization for PCI-E based discrete card through VGA OpRom
(SoC or Mainboard user can't select VGA_ROM_RUN directly because
it's part of choice option).

(Note: Some payloads, like SeaBIOS, are also able to run Option ROMs,
so coreboot does not need to enable VGA_ROM_RUN Kconfig)

For payload like depthcharge, create VGA_ROM_RUN_DEFAULT Kconfig
for mainboard to select design with DGPU where OpROM is embedded
inside the DGPU card.

Allow auto selection of VGA_ROM_RUN_DEFAULT from VGA_BIOS Kconfig.

Also NO_GFX_INIT Kconfig to avoid running VGA_ROM_RUN
by default in case SeaBIOS is used.

TEST=Able to get Pre-OS splash screen with AMD Radeon RX 5700 PCI-E

dbb667ac08 device + util/sconfig: introduce new device gpio
Introduce a new device `gpio` that is going to be used for generic
abstraction of gpio operations in the devicetree.

The general idea behind this is that every chip can have gpios that
shall be accessible in a very generic way by any driver through the
devicetree.

The chip that implements the chip-specific gpio operations has to assign
them to the generic device operations struct, which then gets assigned
to the gpio device during device probing. See CB:48583 for how this gets
done for the SoCs using intelblocks/gpio.

The gpio device then can be added to the devicetree with an alias name
like in the following example:

  chip soc/whateverlake
    device gpio 0 alias soc_gpio on end
    ...
  end

Any driver that requires access to this gpio device needs to have a
device pointer (or multiple) and an option for specifying the gpio to be
used in its chip config like this:

  struct drivers_ipmi_config {
    ...
    DEVTREE_CONST struct device *gpio_dev;
    u16 post_complete_gpio;
    ...
  };

The device `soc_gpio` can then be linked to the chip driver's `gpio_dev`
above by using the syntax `use ... as ...`, which was introduced in
commit 8e1ea52:

  chip drivers/ipmi
    use soc_gpio as gpio_dev
    register "bmc_jumper_gpio" = "GPP_D22"
    ...
  end

The IPMI driver can then use the generic gpio operations without any
knowlege of the chip's specifics:

  unsigned int gpio_val;
  const struct gpio_operations *gpio_ops;
  gpio_ops = dev_get_gpio_ops(conf->gpio_dev);
  gpio_val = gpio_ops->get(conf->bmc_jumper_gpio);

For a full example have a look at CB:48096 and CB:48095.

This change adds the new device type to sconfig and adds generic gpio
operations to the `device_operations` struct. Also, a helper for getting
the gpio operations from a device after checking them for NULL pointers
gets added.

Successfully tested on Supermicro X11SSM-F with CB:48097, X11SSH-TF with
CB:48711 and OCP DeltaLake with CB:48672.

92106b1666 drivers: Replace multiple fill_lb_framebuffer with single instance
Currently it's not possible to add multiple graphics drivers into
one coreboot image. This patch series will fix this issue by providing
a single API that multiple graphics drivers can use.

This is required for platforms that have two graphic cards, but
different graphic drivers, like Intel+Aspeed on server platforms or
Intel+Nvidia on consumer notebooks.

The goal is to remove duplicated fill_fb_framebuffer(), the advertisment
of multiple independent framebuffers in coreboot tables, and better
runtime/build time graphic configuration options.

Replace all duplications of fill_fb_framebuffer and provide a single one
in edid_fill_fb.c. Should not change the current behaviour as still only
one graphic driver can be active at time.

7e3e1ea43f device/pci: Add NULL check for PCI driver's .ops
Add a NULL check and only skip setting the default operations
if `.ops` was set by a driver. It's fairly unlikely that some-
body adds a driver and forgets the `.ops` pointer. So this is
mostly to increase readability: Nobody should have to wonder
if we're missing a NULL-check.

The condition is moved out of the loop to reduce indentation
levels. Alternatively, we could jusk skip drivers that don't
have `.ops` set (i.e. continue the loop).

bf69622256 device: Allow virtual/generic devices under PCI in devicetree
This change allows a generic device to be described in the devicetree
under a PCI device, such as a root port.

Previously any device under a PCI device was expected to also be a PCI
device and that does not allow for a virtual/generic device to be
present, for example to provide ACPI properties for a root port.

The changes are:
- Ignore non-PCI devices found under a PCI device when scanning and do
not print an error for each devfn scanned.
- Don't treat non-PCI devices as leftover and remove them, instead
enable them as a static device.
- Don't attempt to configure a static device in the tree that is not a
PCIe device type.

With these changes it is now possible to have a generic device under a
PCI device, for example in a USB4/TBT root port (PCIe hotplug device)
this generic device will add ACPI properties for the PCIe tunnel routed
to the external port:

device pci 07.0 on
  chip soc/intel/common/block/pcie
    device generic 0 on end
  end
end

TEST=boot on volteer with the USB4 root port devices in chipset.cb and
ensure they are enabled properly and there are no errors printed in the
coreboot log, and that the device properties are created in the SSDT.

e4a7d9f693 device: Add method to configure bus mastering based on Kconfig
The bus master bit is set at many places in coreboot's code, but the
reason for that is not quite clear. We examined not setting the
bus master bit whereever possible and tried booting without it,
which worked fine for internal PCI devices but not for PCIe. As a PCIe
device we used a Samsung M.2 NVMe SSD.

For security reasons, we would like to disable bus mastering where
possible. Depending on the device, bus mastering might get enabled
by the operating system (e.g. for iGPU) and it might be required for
some devices to work properly. However, the idea is to leave it disabled
and configure the IOMMU first before enabling it.

To have some sort of "backwards compatibility", add a method which
configures bus mastering based on an additional config option. Since
CB:42460 makes usage of this treewide, enable it by default to keep the
current behaviour for now.

Tested with Siemens/Chili, a Coffee Lake based platform.

b82b4314ad src: Never set ISA Enable on PCI bridges
Looks like no one really knows what this bit would be useful for, nor
when it would need to be set. Especially if coreboot is setting it even
on PCI *Express* bridges. Digging through git history, nearly all
instances of setting it on PCIe bridges comes from i82801gx, for which
no reason was given as to why this would be needed. The other instances
in Intel code seem to have been, unsurprisingly, copy-pasted.

Drop all uses of this definition and rename it to avoid confusion. The
negation in the name could trick people into setting this bit again.

Tested on Asrock B85M Pro4, no visible difference.
