db199cc073 device/pci_device.c: Make sure the PCI bus has a device
Some SOC add PCI root busses structs at runtime without adding a
device struct to the bus because pci_scan_bus does it. An example
would be xeon_sp which has multiple root busses.

TEST: ocp/deltalake boots again.

777ffff442 device/pci_device.c: Scan only one device for PCIe
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
it. As an optimization, scan only for device 0 in that case.

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.

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.

dbcf7b1621 device/pci_device: Add notion of "hidden" PCI devices
On some SoCs, there are PCI devices that may get hidden from PCI
enumeration by platform firmware. Because the Vendor ID reads back as
0xffffffff, it appears that there is no PCI device located at that BDF.
However, because the device does exist, designers may wish to hang its
PCI resources off of a real __pci_driver, as well as have it participate
in ACPI table generation.

This patch extends the semantics of the 'hidden' keyword in
devicetree.cb. If a device now uses 'hidden' instead of 'on', then it
will be assumed during PCI enumeration that the device indeed does
exist, and it will not be removed as a "leftover device." This allows
child devices to be enumerated correctly and also PCI resources can be
designated from the {read,set}_resources callbacks.

It should be noted that as of this commit, there are precisely 0 devices
using 'hidden' in their devicetree.cb files, so this should be a safe
thing to do.

Later patches will begin moving PCI resources from random places (typically
hung off of fixed SA and LPC) into the PMC device (procedure will vary per-
platform).

76cedd2c29 acpi: Move ACPI table support out of arch/x86 (3/5)
This change moves all ACPI table support in coreboot currently living
under arch/x86 into common code to make it architecture
independent. ACPI table generation is not really tied to any
architecture and hence it makes sense to move this to its own
directory.

In order to make it easier to review, this change is being split into
multiple CLs. This is change 3/5 which basically is generated by
running the following command:
$ git grep -iIl "arch/acpi" | xargs sed -i 's/arch\/acpi/acpi\/acpi/g'

466ca2c1ad Add configurable ramstage support for minimal PCI scanning
This CL has changes that allow us to enable a configurable
ramstage, and one change that allows us to minimize PCI
scanning. Minimal scanning is a frequently requested feature.

To enable it, we add two new variables to src/Kconfig
CONFIGURABLE_RAMSTAGE
is the overall variable controlling other options for minimizing the
ramstage.

MINIMAL_PCI_SCANNING is how we indicate we wish to enable minimal
PCI scanning.

Some devices must be scanned in all cases, such as 0:0.0.

To indicate which devices we must scan, we add a new mandatory
keyword to sconfig

It is used in place of on, off, or hidden, and indicates
a device is enabled and mandatory. Mandatory
devices are always scanned. When MINIMAL_PCI_SCANNING is enabled,
ONLY mandatory devices are scanned.

We further add support in src/device/pci_device.c to manage
both MINIMAL_PCI_SCANNING and mandatory devices.

Finally, to show how this works in practice, we add mandatory
keywords to 3 devices on the qemu-q35.

TEST=
1. This is tested and working on the qemu-q35 target.
2. On CML-Hatch

Before CL:
Total Boot time: ~685ms

After CL:
Total Boot time: ~615ms

cf2ac543a0 pciexp: Add support for allocating PCI express hotplug resources
This change adds support for allocating resources for PCI express hotplug
bridges when PCIEXP_HOTPLUG is selected. By default, this will add 32 PCI
subordinate numbers (buses), 256 MiB of prefetchable memory, 8 MiB of
non-prefetchable memory, and 8 KiB of I/O space to any device with the
PCI_EXP_SLTCAP_HPC bit set in the PCI_EXP_SLTCAP register, which
indicates hot-plugging capability. The resource allocation is configurable,
please see the PCIEXP_HOTPLUG_* variables in src/device/Kconfig.

In order to support the allocation of hotplugged PCI buses, a new field
is added to struct device called hotplug_buses. This is defaulted to
zero, but when set, it adds the hotplug_buses value to the subordinate
value of the PCI bridge. This allows devices to be plugged in and
unplugged after boot.

This code was tested on the System76 Darter Pro (darp6). Before this
change, there are not enough resources allocated to the Thunderbolt
PCI bridge to allow plugging in new devices after boot. This can be
worked around in the Linux kernel by passing a boot param such as:
pci=assign-busses,hpbussize=32,realloc

This change makes it possible to use Thunderbolt hotplugging without
kernel parameters, and attempts to match closely what our motherboard
manufacturer's firmware does by default.

061b90507d device/pci: Enable full 16-bit VGA port i/o decoding
So, the PCI to PCI bridge specification had a pitfall for us:
Originally, when decoding i/o ports for legacy VGA cycles, bridges
should only consider the 10 least significant bits of the port address.
This means all VGA registers were aliased every 1024 ports!
    e.g. 0x3b0 was also decoded as 0x7b0, 0xbb0 etc.

However, it seems, we never reserved the aliased ports, resulting in
silent conflicts we preallocated resources. We neither use much
external VGA nor many i/o ports these days, so nobody noticed.

To avoid this mess, a bridge control bit (VGA16) was introduced in
2003 to enable decoding of 16-bit port addresses. As older systems
seem rather safe and well tested, and newer systems should support
this bit, we'll use it if possible and only warn if not.

With old (AGP era) hardware one will likely encounter a warning like
this:

    found VGA at PCI: 06:00.0
    A bridge on the path doesn't support 16-bit VGA decoding!

This is not generally fatal, but makes unnoticed resource conflicts
more likely.

c544a85d2a lib/coreboot_table: Show splashscreen in lb_table_init
Every vga init implementation needs to cache the framebuffer state
to be able to fill the lb_framebuffer struct later on in the
fill_lb_framebuffer call. Showing the bootsplash afterwards
guarantees to have the same interface into all the vga drivers.

This is by far from ideal, as it only allows for a single driver at
compile-time and should be adapted in the future.

It was tested on the wip razer blade stealth using vgabios @ 1280x1024
and also in Qemu @ 1280x1024.
By default the qemu framebuffer will be initialized in 800x600@32.
This can be overwriten by configuration by setting
CONFIG_DRIVERS_EMULATION_QEMU_BOCHS_{X,Y}RES .

db7a3ae863 src/device/oprom: Fix bootsplash display code for optionroms
So far the bootsplash is only correctly rendered if the framebuffer is
set up as 1024x768@16.
Different resolutions did not show anything, differnent depth resulted
in the distorted images.

This commit removes this limit by using the actual framebuffer resolutions
and combines the code for x86 and yabel.

For the moment the bootsplash is still limited to VGA-OptionROM
framebuffer init.

It was tested in 1280x1024@32 on the wip razer blade stealth using the
intel vgabios.

807803afa2 vboot: remove OPROM-related code
As of CL:1605641, vboot2 code should be used for setting and
checking display init state.  Remove all vboot1 OPROM-related
code, and use the vboot2 display init code which has already
been added in previous commits.

coreboot should not be reading vboot NVRAM flags directly.
Remove the function vboot_wants_oprom(), and instead rely on
display_init_required(), which uses the
VBOOT_WD_FLAG_DISPLAY_INIT value stored in
vboot_working_data.flags, initialized during verstage.
Note that this means in the case of CONFIG_VBOOT=y, the return
value of display_init_required() can only be trusted after
verstage has been executed.  This should not be a problem
assuming that all display initialization occurs in ramstage.
