3bb796bc2c Split CPU_CORTEXA into CPU_CORTEXA8, for the Cortex-A8, and CPU_CORTEXA_MP,
for later Cortex-A CPUs that support the Multiprocessor Extensions. This
will be needed to support both in a single GENERIC kernel while still
being able to only build for a single SoC.

- Read interrupt properties at bus enumeration time and store
   it into global mapping table.
 - At bus_activate_resource() time, given mapping entry is resolved and
   connected to real interrupt source. A copy of mapping entry is attached
   to given resource.
 - At bus_setup_intr() time, mapping entry stored in resource is used
   for delivery of requested interrupt configuration.
 - For MSI/MSIX interrupts, mapping entry is created within
   pci_alloc_msi()/pci_alloc_msix() call.
 - For legacy PCI interrupts, mapping entry must be created within
   pcib_route_interrupt() by pcib driver itself.

b05aea41fa Pass device tree node as a part of gpio_pin_get_by_ofw_XXX API
Current API assumes that "gpios" property belongs to the device's node but for
some binding it's not true: gpiokeys has set of child nodes with this property.

Patch adds new argument instead of replacing device_t because device_t will be
used to track ownership for allocated pins

ee35e13013 INTRNG - redefine struct intr_map_data to avoid headers pollution. Each
struct associated with some type defined in enum intr_map_data_type
must have struct intr_map_data on the top of its own definition now.
When such structs are used, correct type and size must be filled in.

There are three such structs defined in sys/intr.h now. Their
definitions should be moved to corresponding headers by follow-up
commits.

While this change was propagated to all INTRNG like PICs,
pic_map_intr() method implementations were corrected on some places.
For this specific method, it's ensured by a caller that the 'data'
argument passed to this method is never NULL. Also, the return error
values were standardized there.

a5b629647e TEGRA: Fix CPU frequency switching.
The PLL_X, base CPU frequency source, doesn't have a bypass switch and thus
we must use another frequency source for CPU while changing its frequency.
PLL_P is ideal for this, it runs at 480MHz and CPU can be clocked at this
frequency at any CPU voltage.

11cdd44a03 Remove FDT specific parts from INTRNG. Change its interface to make it
universal.

(1) New struct intr_map_data is defined as a container for arbitrary
description of an interrupt used by a device. Typically, an interrupt
number and configuration relevant to an interrupt controller is encoded
in such description. However, any additional information may be encoded
too like a set of cpus on which an interrupt should be enabled or vendor
specific data needed for setup of an interrupt in controller. The struct
intr_map_data itself is meant to be opaque for INTRNG.

(2) An intr_map_irq() function is created which takes an interrupt
controller identification and struct intr_map_data as arguments and
returns global interrupt number which identifies an interrupt.

(3) A set of functions to be used by bus drivers is created as well as
a corresponding set of methods for interrupt controller drivers. These
sets take both struct resource and struct intr_map_data as one of the
arguments. There is a goal to keep struct intr_map_data in struct
resource, however, this way a final solution is not limited to that.

(4) Other small changes are done to reflect new situation.

This is only first step aiming to create stable interface for interrupt
controller drivers. Thus, some temporary solution is taken. Interrupt
descriptions for devices are stored in INTRNG and two specific mapping
function are created to be temporary used by bus drivers. That's why
the struct intr_map_data is not opaque for INTRNG now. This temporary
solution will be replaced by final one in next step.
