These two identifiers were always very confusing. We're not filling and
injecting generators. We are filling SSDTs and injecting into the DSDT.
So drop the `_generator` suffix. Hopefully, this also makes ACPI look a
little less scary.

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

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.

This patch moves the traditional POSIX stdbool.h definitions out from
stdint.h into their own file. This helps for using these definitions in
commonlib code which may be compiled in different environments. For
coreboot everything should chain-include this stuff via types.h anyway
so nothing should change.

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.

This function is duplicated in many AMD northbridge files, and all

copy into device utils and deletes the rest. The function definition
from nb/amd/amdfam10 was chosen to be kept, since it contains several
fixes from commit 59d609217b (AMD fam10: Fix add_more_links) that
the others don't have.
For the ease of diffing, the checkpatch lints and other small cleanups
will be done in a follow-up patch.

Semantics of dev_find_slot() are ill in the sense that
it only works after device enumeration has completed in
ramstage. Plan is to declare it as deprecated.
Introduce pcidev_on_root() and pcidev_path_on_root()
functions to replace cases where this was called with
static argument bus == 0. New implementation only walks
the root bus of the PCI tree, while old one walked
the entire linked list of devices.
Introduce pcidev_path_behind() to replace cases where
argument bus != 0. The required parent node is typically
one of the PCIe root functions that you locate using
pcidev_on_root() above.
New forms are safe to use with early devicetree and
before PCI bus numbers have been assigned.

This commit adds support for describing USB ports in devicetree.cb.
It allows a USB port location to be described in the tree with
configuration information, and ACPI code to be generated that
provides this information to the OS.
A new scan_usb_bus() is added that will scan bridges for devices so
a tree of ports and hubs can be created.
The device address is computed with a 'port type' and a 'port id'
which is flexible for SOC to handle depending on their specific USB
setup and allows USB2 and USB3 ports to be described separately.
For example a board may have devices on two ports, one with a USB2
device and one with a USB3 device, both of which are connected to an
xHCI controller with a root hub:
xHCI

register "name" = ""Root Hub""
device usb 0.0 on

register "name" = ""USB 2.0 Port 0""
device usb 2.0 on end
end
chip drivers/usb/acpi
register "name" = ""USB 3.0 Port 2""
device usb 3.2 on end
end
end
end
end

For broken devices that spuriously advertise ASPM, make it possible to

This further allows compilation units to be re-used without
having to add macro guards because of declarations not being
around in the __SIMPLE_DEVICE__ case. These declarations are for
functions that operate on struct device. struct device is a known
type so just expose the functions using the correct type. Also,
DEVTREE_CONST is empty while in ramstage so there's no reason
to separate the declarations. Lastly, fix up device_util.c to
use the proper types. It's only compiled in ramstage and it only
operates on struct device.

There's no reason to mutate the struct device when determining
the ACPI name for a device. Adjust the function pointer
signature and the respective implementations to use const
struct device.

This patch uses struct device explicitly for the ramstage functions
as that's the actual type it's working on. Additionally, the
declarations for types and functions are fully exposed so that
compliation units don't have to guard certain functions from use
because it's being compiled for multiple stages.

The devicetree data structures have been available in more than just
ramstage and romstage. In order to provide clearer and consistent
semantics two new macros are provided:
1. DEVTREE_EARLY which is true when !ENV_RAMSTAGE
2. DEVTREE_CONST as a replacment for ROMSTAGE_CONST
The ROMSTAGE_CONST attribute is used in the source code to mark
the devicetree data structures as const in early stages even though
it's not just romstage. Therefore, rename the attribute to
DEVTREE_CONST as that's the actual usage. The only place where the
usage was not devicetree related is console_loglevel, but the same
name was used for consistency. Any stage that is not ramstage has
the const C attribute applied when DEVTREE_CONST is used.
