thorpej | 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?).

Call acpi_device_register() / fdtbus_device_register() as approrpriate.

rename of_search_compatible() to of_compatible_lookup().
Standardize on of_compatible_match() for driver matching, and adapt
all call sites.

skrll | 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.
Thanks to martin@ and aymeric@ for testing on parallella and nanosoc
respectively

ryo | cleanup aarch64 mpstart and fdt bootstrap
* arm_cpu_hatch_arg is a bad idea. avoid serializing CPU startup, and eliminate arm_cpu_hatch_arg.
in mpstart, resolve own cpu index using array of cpu_mpidr[] (aarch64)
* add support fdt enable-method "spin-table"
* add support fdt enable-method "brcm,bcm2836-smp" (for 32bit RaspberryPi)
* use arm_fdt_cpu_bootstrap() instead of psci_fdt_bootstrap()
* rename "arm/fdt/psci_fdt.h" to "arm/fdt/psci_fdtvar.h" because of conflict of include file for needs-flag
* add devmap for cpu spin-table of raspberrypi3/aarch64
* no need to force hatch APs for raspberrypi3/arm32 ifndef MULTIPROCESSOR.
* fix to work pmap_extract(kerneltext/data/bss) even if before calling pmap_bootstrap
idea to use cpu_mpidr[] by jmcneill@. reviewd by skrll@. thanks.

riastradh | 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!)

on evbarm/RPI,RPI2, VERBOSE_INIT_ARM had broken.
XPUTC() of evbarm/rpi/rpi*_start.S uses bcm283[567]_platform_early_putchar() and it requires stack.
fixed to allocate stack when starting from rpi*_start.S and a9_mpsubr.S if needed.
to work XPUTC(), need to define VERBOSE_INIT_ARM and EARLYCONS option.
