Furquan Shaikh 931982600d util/sconfig: Re-factor device structure in parse tree
This change re-factors the device structure in parse tree to be able
to support multidev devices just like non-multidev devices.

With this change, every device has a bus under it which is the parent
of all devices that fall on the bus. If there are duplicate entries in
the devicetree, then there will be multiple buses under the device and
each bus will have its own set of children.

The tree starts out with a root device which has a root bus under
it. This is a special device which is created statically and its
parent is its own root bus. When parsing the device tree file, devices
get added under the root bus as children.

Since this change re-organizes the way devicetree is represented, it
gets rid of latestchild and next_sibling pointers from struct
device. Also, the tree traversal to generate static.c is changed to
breadth-first walk instead of using the next_sibling.

Furquan Shaikh c56ae2ffa1 util/sconfig: Get rid of struct header
Now that chips and devices are treated differently in sconfig, this
change gets rid of struct header and add_header function which were
responsible for maintaining list of headers that need to be added to
static.c.

Instead, struct chip is re-factored into struct chip and
struct chip_instance, where chip is a list of unique chips required by
the mainboard whereas chip_instance is an instance of the chip. One
chip can have multiple instances dependending upon the devices in the
system. Also, struct device is updated to hold a pointer to chip
instance instead of the chip structure. This unique list of chips is
then used to add appropriate headers to static.c

Furquan Shaikh 79e8412665 util/sconfig: Re-factor sconfig to not assume chip as device
This change adds a new structure "struct chip" to identify elements of
type chip rather than re-using the structure for device. Until now
chip was treated as a device while generating the parse tree and then
device tree postprocessing skipped over all the chip entries in
children and sibling pointers of device nodes.

With this change, the device tree will only contain struct device in
the parsed tree. It helps by avoiding unnecessary pointers to chip
structure as children or next_sibling and then skipping those elements
in post processing. Every device can then hold a pointer to its chip.

When generating static.c, chip structure is emitted before device
structure to ensure that the device structure has chip within its
scope. Externally, the only visible change in static.c should be the
order in which chip/device elements are emitted i.e. previously all
chips under a particular device were emitted to static.c and then the
devices using those chips. Now, all chips are emitted before all the
devices in static.c

BUG=b:80081934
TEST=Verified that abuild is successful for all boards. Also, verified
that static.c generated for eve, kahlee, scarlet, asrock imb_a180 is
unchanged from before in node definitions.

Duncan Laurie bae9f85ddb devicetree: Add USB device type
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
       |
    RootHub
    |     |
USB2[0]  USB3[2]

device pci 14.0 on
  chip drivers/usb/acpi
    register "name" = ""Root Hub""
    device usb 0.0 on
      chip drivers/usb/acpi
        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

Aaron Durbin e4d7abc0d4 lib: provide clearer devicetree semantics
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.

Duncan Laurie 4650f5baff sconfig: Add a new generic device type
Add support for a basic generic device in the devicetree to bind to a
device that does not have a specific bus, but may need to be described
in tables for the operating system.  For instance some chips may have
various GPIO connections that need described but do not fall under any
other device.

In order to support this export the basic 'scan_static_bus()' that can
be used in a device_operations->scan_bus() method to scan for the generic
devices.

It has been possible to get a semi-generic device by using a fake PNP
device, but that isn't really appropriate for many devices.

Also Re-generate the shipped files for sconfig.  Use flex 2.6.0 to avoid
everything being rewritten.  Clean up the local paths that leak into the

There are no files to build left under AMD nortbridge/x/root_complex
directories. For some cases, even the Kconfig file was no longer sourced.
Remove all such references and empty files.

For devicetree.cb treat component paths with "/root_complex" in them valid
even when the directory does not exists. This is because AMD boards us this
dummy chip component as the root node in their devicetree.cb.

The generated devicetree file static.c remains unchanged.

Stefan Reinauer 57879c9bd1 Make the device tree available in the rom stage
We thought about two ways to do this change. The way we decided to try
was to
1. drop all ops from devices in romstage
2. constify all devices in romstage (make them read-only) so we can
   compile static.c into romstage
3. the device tree "devices" can be used to read configuration from
   the device tree (and nothing else, really)
4. the device tree devices are accessed through struct device * in
   romstage only. device_t stays the typedef to int in romstage
5. Use the same static.c file in ramstage and romstage

We declare structs as follows:
ROMSTAGE_CONST struct bus dev_root_links[];
ROMSTAGE_CONST is const in romstage and empty in ramstage; This
forces all of the device tree into the text area.

So a struct looks like this:
static ROMSTAGE_CONST struct device _dev21 = {
 #ifndef __PRE_RAM__
        .ops = 0,
 #endif
        .bus = &_dev7_links[0],
        .path = {.type=DEVICE_PATH_PCI,{.pci={ .devfn = PCI_DEVFN(0x1c,3)}}},
        .enabled = 0,
        .on_mainboard = 1,
        .subsystem_vendor = 0x1ae0,
        .subsystem_device = 0xc000,
        .link_list = NULL,
        .sibling = &_dev22,
 #ifndef __PRE_RAM__
        .chip_ops = &southbridge_intel_bd82x6x_ops,
 #endif
        .chip_info = &southbridge_intel_bd82x6x_info_10,
        .next=&_dev22
};

Sven Schnelle 0fa50a1990 MPTAPLE: generate from devicetree.cb
This patch adds support for autogenerating the MPTABLE from
devicetree.cb. This is done by a write_smp_table() declared
weak in mpspec.c. If the mainboard doesn't provide it's own
function, this generic implementation is called.

Syntax in devicetree.cb:

ioapic_irq <APICID> <INTA|INTB|INTC|INTD> <INTPIN>

The ioapic_irq directive can be used in pci and pci_domain
devices. If there's no directive, the autogen code traverses
the tree back to the pci_domain and stops at the first device
which such a directive, and use that information to generate the
entry according to PCI IRQ routing rules.

Mainboard and chip Kconfig files have several build options that
are redundant with information in devicetree.cb. This patch enables
sconfig to auto-generate equivalent configuration.

  sconfig -s

Generates mainboard's static.c file, as before.

  sconfig -b

This operation creates mainboard's bootblock init code. By default,
for every chip listed in mainboard/devicetree.cb, if there is a
chip/bootblock.c file, the init function is called.
A mainboard/bootblock.c file can be added to override default
behaviour.

  sconfig -k

This operation generates select -options for component paths.
