MFC r269594, r269596, r269597, r269598, r269605, r269606:
Set ofwbus and simplebus to attach during BUS_PASS_BUS.
Define names that drivers can use to adjust their position relative to other drivers within a BUS_PASS
Adjust ofwbus and simplebus to attach at BUS_PASS_ORDER_MIDDLE, so that a platform can attach some other bus first if necessary.
Set the pl310 L2 cache driver to attach during the middle of BUS_PASS_CPU.
Attach arm generic interrupt and timer drivers in the middle of BUS_PASS_INTERRUPT and BUS_PASS_TIMER, respectively.
Add an arm option, ARM_DEVICE_MULTIPASS, used to opt-in to multi-pass device attachment on arm platforms. If this is defined, nexus attaches early in BUS_PASS_BUS, and other busses and devices attach later, in the pass number they are set up for. Without it defined, nexus attaches in BUS_PASS_DEFAULT and thus so does everything else, which is status quo.

Add FDT matching code to AT91 device drivers.
Better nomatch messages: include compat string. Also, flag devices as disabled in the successful probe message, but leave what that means to the actual driver (no semantic changes).
Fix Embest board name and id.
Honor the disabled status by only grabbing resources and returning when running under FDT in the AT91 SPI driver.

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 kva_free(), or we'd end up always passing it a size of 0
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.

Reimplement fdt_intr_to_rl() in terms of OFW_BUS_MAP_INTR() and OFW_BUS_CONFIG_INTR().
Use bus_space_map() rather than pmap_mapdev() in nexus_activate_resource(), when running on FDT systems. Unmap memory in nexus_deactivate_resource().

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.

Add a new function (OF_getencprop()) that undoes the transformation applied by encode-int. Specifically, it takes a set of 32-bit cell values and changes them to host byte order. Most non-string instances of OF_getprop() should be using this function, which is a no-op on big-endian platforms.
Use the new function all over the place.

Merging of projects/armv6, part 4
r233822: Remove useless and wrong piece of code in fdt_get_range() which i overwrites passed phandle_t node. Modify debug printf in fdt_reg_to_rl() to be consistent (that is, print start and end *virtual* addresses).
r230560: Handle "ranges;" Make fdt_reg_to_rl() responsible for mapping the device memory, instead on just hoping that there's only one simplebus, and using fdt_immr_va as the base VA.
r230315 Add a function to get the PA from range, instead of (ab)using fdt_immr_pa, and use it for the UART driver

Import the common Flattened Device Tree infrastructure.
o fdtbus(4) - the main abstract bus driver for all FDT-compliant systems. This is a direct replacement for the many incompatible bus drivers grouping integrated peripherals on embedded platforms (like obio(4), ocpbus(4) etc.)
o simplebus(4) - bus driver representing ePAPR style 'simple-bus' node, which is an umbrella device for most of the integrated peripherals on a typical system-on-chip device.
o Other components (common routines library, PCI node processing helper functions)
