2d09b07279 Make kernel option KERNVIRTADDR optional, remove it from std.<platform>
files that can use the default value.

It used to be required that the low-order bits of KERNVIRTADDR matched
the low-order bits of the physical load address for all arm platforms.
That hasn't been a requirement for armv6 platforms since FreeBSD 10.
There is no longer any relationship between load addr and KERNVIRTADDR
except that both must be aligned to a 2 MiB boundary.

This change makes the default KERNVIRTADDR value 0xc0000000, and removes the
options from all the platforms that can use the default value.  The default
is now defined in vmparam.h, and that file is now included in a few new
places that reference KERNVIRTADDR, since it may not come in via the
forced-include of opt_global.h on the compile command line.

af3dc4a7ca sys/arm: further adoption of SPDX licensing ID tags.
Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

3210b87554 Remove platform_mp_probe as it's almost identical on most ARM SoCs, and
slightly wrong on the others. We should just check if mp_ncpus is set to
more than one CPU as we may wish to run on a single core even when SMP is
available.

7758916f44 Move ARM_L2_PIPT option to std.armv6 for all armv6 platforms.
Only L2 PIPT cache is supported for __ARM_ARCH >= 6.

In fact, this is just a pure proclamation as this option is used
only in armv4 specific files now.

fa85e32f0c Mark gpio as "optional" in files.mv and edit Marvell's kernconfs
Including arm/mv/gpio.c now depends on 'gpio' device. 'device gpio' was
added to all kernconf files of Marvell boards, except ARMADAXP (dummy
mv_gpio_res definition was removed) and ARMADA38X (not supported yet).

This commit allows to use generic files.mv on A38X.

27f38a8d69 Since r289279 bufinit() uses mp_ncpus, but some architectures set this
variable during mp_start() which is too late.  Move this to mp_setmaxid()
where other architectures set it and move x86 assertions to MI code.

16b2a62ec4 Use pmap_mapdev()/unmapdev() to temporarily map on-chip sram while copying
the startup trampoline code.  The old code allocated a kva page, mapped it
using using pmap_kenter_nocache(), then freed the kva without destroying
the mapping.  This is the only use of pmap_kenter_nocache() in the system,
so redoing this one use of allows it to be garbage collected in the
near future.

47fdf913c1 Avoid using hard-coded SoC's register address in mptramp code for Armada XP
SoC's registers base address may differ between boards
(0xf1000000 or 0xd0000000). Therefore, in order to use
the proper CPU Boot Address Redirect register during SMP
initialization in mptramp the real, physical address has
to be passed to mptramp based on the value from DT.

d0307444ed Fix broken SMP startup on Armada XP after r265694
During Armada's platform_mp_start_ap(), mptramp code
is being copied to the specific physical location (0xffff0000).
Before r265694 the address to which the code should be copied
was equal to the address of mpentry routine that followed the
mptramp in locore.S. Now the mptramp end address should be
exported and used as a copy limit.

aab6f7ed9a Move the declaration for mpentry() into a header file instead of pasting
it into a bunch of different .c files.  Remove declarations for the unused
mptramp() function from everywhere except AramadaXP (and I think it's
really not used there either, because the code that references it appears
to be insanely does-nothing in nature).
