1af789ed11 Add machine/sysreg.h to simplify accessing the system control coprocessor
registers and use it in the ARMv7 CPU functions.

The sysreg.h file has been checked by hand, however it may contain errors
with the comments on when a register was first introduced. The ARMv7 cpu
functions have been checked by compiling both the previous and this version
and comparing the md5 of the object files.

c98a2727cc ddb: allow specifying the exact address of the symtab and strtab
When the FreeBSD kernel is loaded from Xen the symtab and strtab are
not loaded the same way as the native boot loader. This patch adds
three new global variables to ddb that can be used to specify the
exact position and size of those tables, so they can be directly used
as parameters to db_add_symbol_table. A new helper is introduced, so callers
that used to set ksym_start and ksym_end can use this helper to set the new
variables.

It also adds support for loading them from the Xen PVH port, that was
previously missing those tables.

ddb/db_main.c:
 - Add three new global variables: ksymtab, kstrtab, ksymtab_size that
   can be used to specify the position and size of the symtab and
   strtab.
 - Use those new variables in db_init in order to call db_add_symbol_table.
 - Move the logic in db_init to db_fetch_symtab in order to set ksymtab,
   kstrtab, ksymtab_size from ksym_start and ksym_end.

ddb/ddb.h:
 - Add prototype for db_fetch_ksymtab.
 - Declate the extern variables ksymtab, kstrtab and ksymtab_size.

x86/xen/pv.c:
 - Add support for finding the symtab and strtab when booted as a Xen
   PVH guest. Since Xen loads the symtab and strtab as NetBSD expects
   to find them we have to adapt and use the same method.

6048caab6b Make the ARM MPCore Timer driver work with published standard FDT bindings.
We've always considered the mpcore timers to be a single monolithic device
and we defined our own fdt binding for it with our own compat string.  The
published bindings treat the timers as two separate devices, a global
timer and a "timer-watchdog" device for the per-cpu private timers.  Thus
our binding has two tuples in the regs property, one set of registers for
the global timer and one for the private timers.  The published bindings
have two separate devices, each with a single set of registers.  (Note that
we don't use the optional watchdog feature of the hardware.)

These changes add the compat strings for the published bindings.  If our
own compat string appears, we expect to get two sets of memory resources.
For the published bindings, there's only one set of memory resources, and
only the private timers have an associated interrupt.

The other major change is that there can no longer be a single global var
for the softc pointer because now there may be multiple devices at
runtime.  Since the global timer is used only as a timecounter and the
private timers only as eventtimers, and there will only be one of each,
those are now the pointers which are global, and the priv fields of those
structures backlink to the device softc.

952ded804e Use gic_decode_fdt() rather than a local routine to parse fdt interrupt
properties.  Move fdt_pic_table and fdt_fixup_table into imx6_machdep.c,

0e390441a7 Add a common routine for parsing FDT data describing an ARM GIC interrupt.
In the fdt data we've written for ourselves, the interrupt properties
for GIC interrupts have just been a bare interrupt number.  In standard
data that conforms to the published bindings, GIC interrupt properties
contain 3-tuples that describe the interrupt as shared vs private, the
interrupt number within the shared/private address space, and configuration
info such as level vs edge triggered.

The new gic_decode_fdt() function parses both types of data, based on the
#interrupt-cells property.  Previously, each platform implemented a decode
routine and put a pointer to it into fdt_pic_table.  Now they can just
list this function in their table instead if they use arm/gic.c.

67993f6aa7 Fix an undefined variable that was accidentally not causing an error.
The code had references to both intr_offset and intr_parent variable names
as referring to the parent interrupt node.  The intr_parent variable
wasn't actually defined anywhere, but the only references to it were as
an argument to a macro that didn't use that argument in expansion, so
the undefined variable accidentally didn't cause an error.

The intr_parent name makes more sense in context, so change all occurrances
of intr_offset to intr_parent.
