Step towards modularizing the Flattened Device Tree code.

Define attributes for each of the specific device bindings: clock,
dai, dma, gpio, i2c, iommu, mbox, mmc_pwrseq, phy, power, power domain,
pwm, regulator, reset controller, spi, system controller, pin
controller. Include these support files only if either a provider
or consumer with one of these attributes is present in the kernel
config.

Add the necessary attributes to the device / attach declarations for
each provider and consumer.

There are some bindings that are consumed by generic code (iommu, pinctrl,
power, power domain). Provide weak stubs for these routines to handle
situations where there is no provider.

No actual code changed; NFCI.

tegra_xusb: fix xusb static firmware build

To work around objcopy and ld now being unable to create a EABI5 object
from a binary, use the assembler directive .incbin in inline assembly
to pull in the firmware blob.

This also probably makes TEGRA210_XUSB_BIN_STATIC actually work.

tegra_xusb depends on firmload.

Make the dependency explicit, do not rely on some random USB device to
pull it in.

Remove unused needs-flag

Use psci_fdt_bootstrap for MP spinup on Tegra210.

Add basic tegra210 xusbpad driver, shorten tegra*xusbpad driver names to
tegra*xpad to fit in dv_xname

The xusbpad driver is tegra 124 specific so split it out into a separate
driver. Add (not yet working) tegra 210 support to the xusb driver.

Add support for NVIDIA Tegra X1.

Attach Tegra124 DVFS to /cpus/cpu0 now that another driver is claiming the
/cpus node.

Fix VERBOSE_INIT_ARM build with TEGRA kernel.

Add a facility for platform-specific callbacks and use it to remove most
of the Tegra-specific code from tegra_machdep.c.

Platform code matches on the compatible property of the root ("/") DT node
and allows for chip-specific implementations of the following:

- devmap: Return a 0-terminated list of static device map entries.
- bootstrap: Early initialization of platform-specific facilities.
- early_putchar: Provides an implementation of putchar for use in early
debug messages.
- device_register: Platform-specific device register callback.
- reset: Platform-specific CPU reset implementation.
- consinit: Platform-specific console init implementation.

Enumerate CPUs, GIC, and generic timer using FDT data instead of relying
on hard-coded tables in mainbus.

Remove HOST1X and AHB_A2 from pmap_devmap

Use GEM for memory management. Fixes a couple issues while here:
- No longer needs to allocate 35MB (!) for framebuffer console.
- Allows xrandr to switch to modes larger than the framebuffer console.
- Removes hack that redirected mmap calls to wsdisplay0

Fix another build

Change ap_mpstart to return non-zero value if any/all APs don't start.

Provide generic start code that assumes the MMU is off and caches are
disabled as per the linux booting protocol for ARMv6 and ARMv7 boards.
u-boot image type should be changed to 'linux' for correct behaviour.

The new start code builds a minimal "bootstrap" L1PT with cached access
disabled and uses the same table for all processors. AP startup is
performed in less steps and more code is written in C.

The bootstrap tables and stack are placed into an (orphaned) section
"_init_memory" which is given to uvm when it is no longer used.

Various kernels have been converted to use this code and tested. Some
boards were provided by TNF. Thanks!

The GENERIC kernel now boots on boards using the TEGRA, SUNXI and EXYNOS
kernels. The GENERIC kernel will also work on RPI2 using u-boot.

tegra124_car(4): Attach rndsource synchronously.

It looks like the original motivation for deferring to
config_interrupts was to wait until softint_establish worked. But
this no longer needs to use softints to deliver the entropy, so
that's moot.

Doing this synchronously gives us a better chance for more entropy
earlier.

tegra124_car(4): No need for rnd lock -- delete it.

This only ever reads from a single device register, so no need to
serialize access.

source.

branches: 1.15.8;
Merge thorpej-cfargs branch:

Simplify and make extensible the config_search() / config_found() /
config_attach() interfaces: rather than having different variants for
which arguments you want pass along, just have a single call that
takes a variadic list of tag-value arguments.

Adjust all call sites:
- Simplify wherever possible; don't pass along arguments that aren't
actually needed.
- Don't be explicit about what interface attribute is attaching if
the device only has one. (More simplification.)
- Add a config_probe() function to be used in indirect configuiration
situations, making is visibly easier to see when indirect config is
in play, and allowing for future change in semantics. (As of now,
this is just a wrapper around config_match(), but that is an
implementation detail.)

Remove unnecessary or redundant interface attributes where they're not
needed.

There are currently 5 "cfargs" defined:
- CFARG_SUBMATCH (submatch function for direct config)
- CFARG_SEARCH (search function for indirect config)
- CFARG_IATTR (interface attribte)
- CFARG_LOCATORS (locators array)
- CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles)

...and a sentinel value CFARG_EOL.

Add some extra sanity checking to ensure that interface attributes
aren't ambiguous.

Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark
ports to associate those device handles with device_t instance. This
will trickle trough to more places over time (need back-end for pre-OFW
Sun OBP; any others?).

SDMMC clock input is PLLP (408 MHz). Set input divisor to 2 to get a
204 MHz input for the SDHC, which is just below the maximum supported
frequency for SDR104.

Add a basic driver for the Clock and Reset controller, use it to determine
CPU frequency.

Merge thorpej-cfargs branch:

Simplify and make extensible the config_search() / config_found() /
config_attach() interfaces: rather than having different variants for
which arguments you want pass along, just have a single call that
takes a variadic list of tag-value arguments.

Adjust all call sites:
- Simplify wherever possible; don't pass along arguments that aren't
actually needed.
- Don't be explicit about what interface attribute is attaching if
the device only has one. (More simplification.)
- Add a config_probe() function to be used in indirect configuiration
situations, making is visibly easier to see when indirect config is
in play, and allowing for future change in semantics. (As of now,
this is just a wrapper around config_match(), but that is an
implementation detail.)

Remove unnecessary or redundant interface attributes where they're not
needed.

There are currently 5 "cfargs" defined:
- CFARG_SUBMATCH (submatch function for direct config)
- CFARG_SEARCH (search function for indirect config)
- CFARG_IATTR (interface attribte)
- CFARG_LOCATORS (locators array)
- CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles)

...and a sentinel value CFARG_EOL.

Add some extra sanity checking to ensure that interface attributes
aren't ambiguous.

Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark
ports to associate those device handles with device_t instance. This
will trickle trough to more places over time (need back-end for pre-OFW
Sun OBP; any others?).

Stop potential misuse of vendor names and USB vendor IDs in root hub
device and string descriptors.

Firstly: Few vendors have identical PCI-SIG vendor IDs and USB-IF vendor
IDs. As such, using the PCI vendor ID as a USB vendor ID may trample
on whomever is allocated that USB vendor ID.

Secondly: The vendor of the host controller hardware implementation has
little to nothing to do with our usbroothub implementation. Thus we
should not potentially associate any problems therewith to such third
party.

This change will result in root hubs being identified by USB Vendor ID
0x0000. Root hub vendor string will now be "NetBSD" (or, specifically:
ostype). Product ID (0x0000) and product strings remain unchanged.

use fdtbus_intr_establish_xname

Change fdtbus_register_i2c_controller() to directly register the i2c_tag_t,
rather than the device and a set of functions (the only of which was to
return the i2c_tag_t anyway). Previously, this assumed only a single
i2c controller node per device_t, which is not true with an i2c mux.

branches: 1.23.8;
Use a separate lock (not the i2c bus lock) to synchronize with the
interrupt handler. This in all liklihood fixes a deadlock bug that
necessitated forcing I2C_F_POLL in tegra_i2c_exec() (someone who has
the hardware should test removing that line).

Also includes the changes for:

Cleanup i2c bus acquire / release, centralizing all of the logic into
iic_acquire_bus() / iic_release_bus(). "acquire" and "release" hooks
no longer need to be provided by back-end controller drivers (only if
they need special handling, e.g. powering on the i2c controller).
This results in the removal of a bunch of rendundant code from each
back-end controller driver.

Assert that we are not in hard interrupt context in iic_acquire_bus(),
iic_exec(), and iic_release_bus().

Disallow 0-byte transfers and suppress timeout messages

Rename min/max -> uimin/uimax for better honesty.

These functions are defined on unsigned int. The generic name
min/max should not silently truncate to 32 bits on 64-bit systems.
This is purely a name change -- no functional change intended.

HOWEVER! Some subsystems have

#define min(a, b) ((a) < (b) ? (a) : (b))
#define max(a, b) ((a) > (b) ? (a) : (b))

even though our standard name for that is MIN/MAX. Although these
may invite multiple evaluation bugs, these do _not_ cause integer
truncation.

To avoid `fixing' these cases, I first changed the name in libkern,
and then compile-tested every file where min/max occurred in order to
confirm that it failed -- and thus confirm that nothing shadowed
min/max -- before changing it.

I have left a handful of bootloaders that are too annoying to
compile-test, and some dead code:

cobalt ews4800mips hp300 hppa ia64 luna68k vax
acorn32/if_ie.c (not included in any kernels)
macppc/if_gm.c (superseded by gem(4))

It should be easy to fix the fallout once identified -- this way of
doing things fails safe, and the goal here, after all, is to _avoid_
silent integer truncations, not introduce them.

Maybe one day we can reintroduce min/max as type-generic things that
never silently truncate. But we should avoid doing that for a while,
so that existing code has a chance to be detected by the compiler for
conversion to uimin/uimax without changing the semantics until we can
properly audit it all. (Who knows, maybe in some cases integer
truncation is actually intended!)

FDT: Interrupts -- add support for interrupt maps

The mct on exynos uses an interrupt map so we add support now. Devices
represent their interrupts either through a combination of interrupt-parent
and interrupts properties, where the 'interrupts' property is an array of
one or more interrupt specifiers; or through a combination of an
interrupt-parent that points to an interrupt-map, where the interrupt-map
contains 2 or more entries consisting of an index, a pointer to an
interrupt-controller, and a specifier for that controller.

This code adds the ability to walk the interrupt-map and return a specifier.
Unfortunately, the addition requires changing the interface to the
interrupt-controllers' _establish and _intstr functions, so this check in
contains a rototill of the three existing fdt interrupt controllers to use
the new interface.

branches: 1.37.2; 1.37.4;
Merge thorpej-cfargs branch:

Simplify and make extensible the config_search() / config_found() /
config_attach() interfaces: rather than having different variants for
which arguments you want pass along, just have a single call that
takes a variadic list of tag-value arguments.

Adjust all call sites:
- Simplify wherever possible; don't pass along arguments that aren't
actually needed.
- Don't be explicit about what interface attribute is attaching if
the device only has one. (More simplification.)
- Add a config_probe() function to be used in indirect configuiration
situations, making is visibly easier to see when indirect config is
in play, and allowing for future change in semantics. (As of now,
this is just a wrapper around config_match(), but that is an
implementation detail.)

Remove unnecessary or redundant interface attributes where they're not
needed.

There are currently 5 "cfargs" defined:
- CFARG_SUBMATCH (submatch function for direct config)
- CFARG_SEARCH (search function for indirect config)
- CFARG_IATTR (interface attribte)
- CFARG_LOCATORS (locators array)
- CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles)

...and a sentinel value CFARG_EOL.

Add some extra sanity checking to ensure that interface attributes
aren't ambiguous.

Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark
ports to associate those device handles with device_t instance. This
will trickle trough to more places over time (need back-end for pre-OFW
Sun OBP; any others?).
