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.

5b3779aaee Add a table to map from the FreeBSD CPUID space to the GIC CPUID space. On
many SoCs these two are the same, however there is no requirement for this
to be the case, e.g. on the ARM Juno we boot on what the GIC thinks of as
CPU 2, but FreeBSD numbers it CPU 0.

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.

4e5b50116d Fix fallout from r292180 (Dec 2015)... ensure that every driver which has
a DRIVER_MODULE() referencing mmc_driver has a MODULE_DEPEND() on mmc.  This
is because the kernel linker only searches for symbols in dependent modules,
so loading sdhci_pci (and other bus-flavors of sdhci) would fail when mmc
was not compiled into the kernel (even if you hand-loaded mmc first).

(Thanks to jilles@ for providing the vital clue about the kernel linker.)

720f47c9ed Use uintmax_t (typedef'd to rman_res_t type) for rman ranges.
On some architectures, u_long isn't large enough for resource definitions.
Particularly, powerpc and arm allow 36-bit (or larger) physical addresses, but
type `long' is only 32-bit.  This extends rman's resources to uintmax_t.  With
this change, any resource can feasibly be placed anywhere in physical memory
(within the constraints of the driver).

Why uintmax_t and not something machine dependent, or uint64_t?  Though it's
possible for uintmax_t to grow, it's highly unlikely it will become 128-bit on
32-bit architectures.  64-bit architectures should have plenty of RAM to absorb
the increase on resource sizes if and when this occurs, and the number of
resources on memory-constrained systems should be sufficiently small as to not
pose a drastic overhead.  That being said, uintmax_t was chosen for source
clarity.  If it's specified as uint64_t, all printf()-like calls would either
need casts to uintmax_t, or be littered with PRI*64 macros.  Casts to uintmax_t
aren't horrible, but it would also bake into the API for
resource_list_print_type() either a hidden assumption that entries get cast to
uintmax_t for printing, or these calls would need the PRI*64 macros.  Since
source code is meant to be read more often than written, I chose the clearest
path of simply using uintmax_t.

Tested on a PowerPC p5020-based board, which places all device resources in
0xfxxxxxxxx, and has 8GB RAM.

a5df0b9c3f Add support for dual emac mode.
In dual emac mode, the CPSW subsystem provides two independent ethernets.

This is implemented (as recommended by TI's TRM) with a mixture of switch
settings (vlans) and specific features of CPSW subsystem.

The driver was splitted to accommodate the shared parts (RX and TX rings
for example) while it still provides two independent ethernets.

Each of the ethernet ports driver has it's own set of MDIO registers among
the other private settings.

Previously this driver always operate in promisc mode, now the Switch ALE
(address table entry) is properly initialized and enabled.

The driver is also tested (and known to work) with both ports operating in
single port mode (active_slave 0 or 1).

Tested on uBMC (dual emac mode, both ports in single mode, giga and fast
ethernet) and BBB (single port, fast ethernet).

- added dummy MSI_IRQ, ERR_IRQ defines for Armada38x
- MPIC driver was added to files.armada38x, ARM_INTRNG option enabled in
  kernconf file and regs of MPIC corrected in dts file.

Instead of modifying Armada38X DTS, offsets to CPU registers defined in
driver were changed. That required restoring 'reg' property of mpic node
in ArmadaXP to state compliant with Linux DTS.

Additionally, required ARM_INTRNG definitions were added to mv_common.c.
