6a336d045d Start to remove XScale support from the ARMv4/v5 pmap. Support for XScale
has been removed from the kernel so we can remove it from here to help
simplify the code.

4cde6a5313 Add support for pmap_enter(..., psind=1) to the armv6 pmap. In other words,
add support for explicitly requesting that pmap_enter() create a 1 MB page
mapping.  (Essentially, this feature allows the machine-independent layer
to create superpage mappings preemptively, and not wait for automatic
promotion to occur.)

Export pmap_ps_enabled() to the machine-independent layer.

Add a flag to pmap_pv_insert_pte1() that specifies whether it should fail
or reclaim a PV entry when one is not available.

Refactor pmap_enter_pte1() into two functions, one by the same name, that
is a general-purpose function for creating pte1 mappings, and another,
pmap_enter_1mpage(), that is used to prefault 1 MB read- and/or execute-
only mappings for execve(2), mmap(2), and shmat(2).

In addition, as an optimization to pmap_enter(..., psind=0), eliminate the
use of pte2_is_managed() from pmap_enter().  Unlike the x86 pmap
implementations, armv6 does not have a managed bit defined within the PTE.
So, pte2_is_managed() is actually a call to PHYS_TO_VM_PAGE(), which is O(n)
in the number of vm_phys_segs[].  All but one call to PHYS_TO_VM_PAGE() in
pmap_enter() can be avoided.

5836e9a6b2 aw_sid: Add nvmem interface
Rework aw_sid so it can work with the nvmem interface.
Each SoC expose a set of fuses (for now rootkey/boardid and, if available,
the thermal calibration data). A fuse can be private or public, reading private
fuse needs to be done via some registers instead of reading directly.
Each fuse is exposed as a sysctl.
For now leave the possibility for a driver to read any fuse without using
the nvmem interface as the awg and emac driver use this to generate a mac
address.

96b23bde06 Prepare for adding psind == 1 support to armv6's pmap_enter().
Precompute the new PTE before entering the critical section.

Eliminate duplication of the pmap and pv list unlock operations in
pmap_enter() by implementing a single return path.  Otherwise, the
duplication will only increase with the upcoming support for psind == 1.

fba826ec00 Remove xscale support.
As discussed in arm@.  This is a scaled back version of the prior
commit because xscale is overlaoded in places to mean armv5 or
similar.  The OLD XSCALE stuff hasn't been useful in a while. The
original committer (cognet@) was the only one that had boards for
it. He's blessed this removal. Newer XSCALE (GUMSTIX) is for hardware
that's quite old. After discussion on arm@, it was clear there was no
support for keeping it.

e572e5e488 Remove Cavium/Econa CNS11xx support.
This port hasn't been updated since it was committed, apart from
housekeeping. There's no known users, and the known hardware for
this port is too thin to run FreeBSD/arm these days well.

This also removes the last armv4 port. We've had no reports of armv4
systems working since FreeBSD 8. All the kernel support for armv4 has
not been removed since it's too intertwined with armv5 support (which
remains in the tree).

fbdea4b3c3 Raise a proper SIGTRAP / TRAP_TRACE signal for a PT_STEP step on arm.
Previously, a step by PT_STEP resulted in no signal being raised to
the debugger so that a step was silently completed with the program
continuing to execute after the step.  Fix by raising a SIGTRAP
signal with TRAP_TRACE as the signal code.

To simplify the error handling cases (if ptrace_clear_single_step()
fails, etc.) move the handling of PTRACE_BREAKPOINT into the
gdb_trapper() function.  If ptrace_clear_single_step() fails,
gdb_trapper() won't claim the fault, and the default case of
SIGILL / ILL_OPC will be used.
