MFC r274249, r274484, r275583:

MFC 265852: Map device memory using PTE_DEVICE rather than PTE_NOCACHE.

Add the imx sdhci controller.

Move Open Firmware device root on PowerPC, ARM, and MIPS systems to
a sub-node of nexus (ofwbus) rather than direct attach under nexus. This
fixes FDT on x86 and will make coexistence with ACPI on ARM systems easier.
SPARC is unchanged.

Add the missing ')' at end of sentence. Reword it to use a more common idiom.

Pass the kernel physical address to initarm through the boot param struct.

Make functions only used in vfp.c static, and remove vfp_enable.

Fix __syscall on armeb EABI. As it returns a 64-bit value it needs to
place 32-bit data in r1, not r0. 64-bit data is already packed correctly.

Use abp_physaddr for the physical address over KERNPHYSADDR. This helps us
remove the need to load the kernel at a fixed address.

Remove references to PHYSADDR where it's used only in debugging output.

Dynamically generate the page table. This will allow us to detect the
physical address we are loaded at to change the mapping.

Open Firmware interrupt specifiers can consist of arbitrary-length byte
strings and include arbitrary information (IRQ line/domain/sense). When the
ofw_bus_map_intr() API was introduced, it assumed that, as on most systems,
these were either 1 cell, containing an interrupt line, or 2, containing
a line number plus a sense code. It turns out a non-negligible number of
ARM systems use 3 (or even 4!) cells for interrupts, so make this more
general.

Provide a simpler and more standards-compliant simplebus implementation to
get the Routerboard 800 up and running with the vendor device tree. This
does not implement some BERI-specific features (which hopefully won't be
necessary soon), so move the old code to mips/beri, with a higher attach
priority when built, until MIPS interrupt domain support is rearranged.

Allow nesting of simplebuses.

Add a set of helpers (ofw_bus_get_status() and ofw_bus_status_okay()) to
process "status" properties of OF nodes.

Fix one remnant endian flaw in nexus.

Add common bus_space tag definition shared for most supported ARMv6/v7 SoCs.
Correct license statements to reflect the fact that these files were all
derived from sys/arm/mv/bus_space.c.

In pmap_unmapdev(), remember the size, and use that as an argument to

In pmap_mapdev(), first check whether a static mapping exists,

Convert TI static device mapping to use the new arm_devmap_add_entry(),

Use the common armv6 fdt_bus_tag defintion for tegra instead of a local copy.

Eliminate use of fdt_immr_addr(), it's not needed for tegra

Convert lpc from using fdt_immr style to arm_devmap_add_entry() to make
static device mappings.

Retire machine/fdt.h as a header used by MI code, as its function is now
obsolete. This involves the following pieces:
- Remove it entirely on PowerPC, where it is not used by MD code either
- Remove all references to machine/fdt.h in non-architecture-specific code
(aside from uart_cpu_fdt.c, shared by ARM and MIPS, and so is somewhat
non-arch-specific).
- Fix code relying on header pollution from machine/fdt.h includes
- Legacy fdtbus.c (still used on x86 FDT systems) now passes resource
requests to its parent (nexus). This allows x86 FDT devices to allocate
both memory and IO requests and removes the last notionally MI use of
fdtbus_bs_tag.
- On those architectures that retain a machine/fdt.h, unused bits like
FDT_MAP_IRQ and FDT_INTR_MAX have been removed.

Add #include <machine/fdt.h> to a few files that used to get it via pollution

Enable the mv cesa security/crypto device by providing the required property
in the dts source, and adding the right devices to the kernel config.

Remove dev/fdt/fdt_pci.c, which was code specific to Marvell ARM SoCs,
related to setting up static device mappings. Since it was only used by
arm/mv/mv_pci.c, it's now just static functions within that file, plus
one public function that gets called only from arm/mv/mv_machdep.c.

Switch RPi to using arm_devmap_add_entry() to set up static device mapping.

Allow 'no static device mappings' to potentially work.

Don't try to find a static mapping before calling pmap_mapdev(), that logic
is now part of pmap_mapdev() and doesn't need to be duplicated here.

Switch a10 to using arm_devmap_add_entry() to set up static device mapping.

The kernel stack guard pages are only below the stack pointer, not above.

Remove unnecessary double-setting of the thread's onfault state in
copyinstr().

Open Firmware mandates that certain cross-references, in particular those
in /chosen, be ihandles. The ePAPR spec makes those cross-reference phandles,
since FDT has no concept of ihandles. Have the OF FDT CI module interpret
queries about ihandles as cross-reference phandles.

Real OF systems have an ihandle under /chosen/stdout, not a phandle. Use
the right type.

Rearchitect platform memory map parsing to make it less
Open Firmware-centric.

Remove fdtbus_bs_tag definition, which is now obsolete. The remainder of
this file is also slated for future demolition.

Return the correct IEEE 1275 code for "nextprop".

Use the common Open Firmware PCI interrupt routing code instead of the
duplicate version in dev/fdt.

Configure interrupt sense based on device tree information.

Simplify the ofw_bus_lookup_imap() API slightly: make it allocate maskbuf
internally instead of requiring the caller to allocate it.

Teach nexus(4) about Open Firmware (e.g. FDT) on ARM and MIPS, retiring
fdtbus in most cases.

Make OF_nextprop() work correctly for FDT by using the libfdt
fdt_next_property_offset() API.

Do not panic if pmap_mincore() is called.

An addendum: it is possible, though of questionable utility, for a node
to have no properties at all.
Add definition for the Atheros 8021 gigabit PHY.

Consolidate Apple firmware hacks and improve them by switching on the
presence of mac-io devices in the tree, which uniquely identifies Apple
hardware.

Allow OF_decode_addr() to also be able to map resources on big-endian
devices.

Make tsec work with the device tree present on the RB800.

Be more flexible about which compatible strings to accept. This brings up
the PCI Express bus on the RB800 using the firmware device tree.

Rename the "bare" platform "mpc85xx", which is what it actually is, and
add actual platform probing based on PVR.

MFC r258779,r258780,r258787,r258822:

Fix undefined behavior: (1 << 31) is not defined as 1 is an int and this
shifts into the sign bit. Instead use (1U << 31) which gets the
expected result.

Similar to the (1 << 31) case it is not defined to do (2 << 30).

This fix is not ideal as it assumes a 32 bit int, but does fix the issue
for most cases.

A similar change was made in OpenBSD.

Implement MSI support.

MSI are implemented via Inbound Shared Doorbell 1 interrupts. Interrupts
are triggered by writing to Software Triggered Interrupt registeri (PCIe
card using physical address of this register in BAR0 space). There are 32
interrupts available. It can be increased by using Doorbell 2 and
Doorbell 3 registers to 96 interrupts.

Add Marvell ARMADA XP support

- There's no need to overwrite the default device method with the default
one. Interestingly, these are actually the default for quite some time
(bus_generic_driver_added(9) since r52045 and bus_generic_print_child(9)
since r52045) but even recently added device drivers do this unnecessarily.
Discussed with: jhb, marcel
- While at it, use DEVMETHOD_END.

- Also while at it, use __FBSDID.

The FDT describes the host controller directly. There's no need to
get properties from the parent. The parent is in fact the FDT bus
itself and will therefore not have the properties we're looking
for.

Convert Marvell ARM platforms to FDT convention.

The following systems are involved:

- DB-88F5182
- DB-88F5281
- DB-88F6281
- DB-78100
- SheevaPlug

This overhaul covers the following major changes:

- All integrated peripherals drivers for Marvell ARM SoC, which are
currently in the FreeBSD source tree are reworked and adjusted so they
derive config data out of the device tree blob (instead of hard coded /
tabelarized values).

- Since the common FDT infrastrucutre (fdtbus, simplebus) is used we say
good by to obio / mbus drivers and numerous hard-coded config data.

Note that world needs to be built WITH_FDT for the affected platforms.
