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

Justin TerAvest ca2ed9f450 sconfig: Add a new mmio resource type
Add support for a mmio resource in the devicetree to allow
memory-mapped IO addresses to be assigned to given values.

AMD platforms perform a significant amount of configuration through
these MMIO addresses, including I2C bus configuration.

Furquan Shaikh e67002968b sconfig: Add a new "SPI" device type
Update sconfig lex and yacc files to add support for a new "SPI" device
type in the devicetree. SPI device takes only parameter i.e. chip select
number for the device on the SPI bus.

Re-generate the shipped files for sconfig using flex 2.6.0 and bison
3.0.4 (make CONFIG_SCONFIG_GENPARSER=1). Clean up local paths that leak
into generated files.

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
generated configs.

The name lapic_cluster is a bit misleading, since the construct is not local
APIC specific by concept. As implementations and hardware change, be more
generic about our naming. This will allow us to support non-x86 systems without
adding new keywords.

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.

Sven Schnelle 270a908646 Add subsystemid option to sconfig
Allow user to add 'subsystemid <vendor> <device> [inherit]' to devicetree.cb for
PCI and PCI domain devices.

Example:

	device pci 00.0 on
	       subsystemid dead beef
	end

If the user wants to have this ID inherited to all subdevices/functions,
he can add 'inherit', like in the following example:

	device pci 00.0 on
	       subsystemid dead beef inherit
	end

If the user don't want to inherit a Subsystem for a single device, he can
specify 'subsystemid 0 0' on this particular device.
