Keyword substitution: kv
Default branch: MAIN

Rename ARM_PLATFORM to FDT_PLATFORM and make it available outside arm.

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?).

Sync with HEAD.

- FDT device enumeration now sets the device handle using CFARG_DEVHANDLE.
- fdtbus_device_register() is now obsolete, so G/C it.
- of_device_register() is now obsolete, so G/C it.

Fix build

Call acpi_device_register() / fdtbus_device_register() as approrpriate.

Retire arm_[di]sb in favour of the isb() and dsb(sy) macro invocations.

Get rid of a4x bus_space tag from fdtbus_attach_args. The only consumer
of this was various com(4) glue so modify all of that to use the new
com_init_regs_stride instead.

Add support for KASAN on ARMv[67]

Thanks to maxv for many pointers and reviews.

Mostly merge changes from HEAD upto 20200411

Merge changes from current as of 20200406

Sync with head.

Various updates and improvements to cpu start up on arm/aarch64

- start sharing more code around the AP startup messaging.
- call arm_cpu_topology_set early so that ci_core_id is available for
  drivers, e.g. bcm2835_intr.c
- both arm and aarch64 now have
  - a static cpu_info_store array
  - the same arm_cpu_{hatched,mbox}

No need for console=fb handling with WSDISPLAY_MULTICONS

Sync with HEAD

Fix build

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

Sync with HEAD, resolve a couple of conflicts

Retire fdt_putchar and ap_early_put_char in favour of uartputc.

Sync with head

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

and change variable name from armv7_generic_dma_tag to arm_generic_dma_tag

no functional change. (preliminary changes for merging aarch64)

Add SMP support to VEXPRESS_A15 kernel. Enable with '-smp 2' on qemu
command line.

Switch VEXPRESS_A15 kernel to use FDT and GENERIC.common. The dtb for this
kernel can be found in the sysutils/dtb-arm-vexpress package as
vexpress-v2p-ca15-tc1.dtb
