8839e0e9f3 Make the GPIO children attach to the first unit available and not only to
unit 0.

It seems that this 'simplification' was copied to all GPIO drivers in tree.

This fix a bug where a GPIO controller could fail to attach its children
(gpioc and gpiobus) if another GPIO driver attach first.

27521ff8e4 Add the start of the ARM platform code. This is based on the PowerPC
platform code, it is expected these will be merged in the future when the
ARM code is more complete.

Until more boards can be tested only use this with the Raspberry Pi and
rrename the functions on the other SoCs.

5e4e1d4995 Eliminate irq_dispatch.S. Move the data items it contained into arm/intr.c
and the functionality it provided into arm/exception.S.  Rename the main
irq handling routine from arm_handler_execute() to arm_irq_handler() to
make it more congruent with how other exception handlers are named, and
also update its signature to reflect what has long been reality: it is
passed just a trapframe pointer, no interrupt number argument.

f0455d6562 Replace many pasted identical definitions of cpu_initclocks() with a common
implementation in arm/machdep.c.  Most arm platforms either don't need to
do anything, or just need to call the standard eventtimer init routines.
A generic implementation that does that is now provided via weak linkage.
Any platform that needs to do something different can provide a its own
implementation to override the generic one.

add35ed5b8 Follow r261352 by updating all drivers which are children of simplebus
to check the status property in their probe routines.

Simplebus used to only instantiate its children whose status="okay"
but that was improper behavior, fixed in r261352.  Now that it doesn't
check anymore and probes all its children; the children all have to
do the check because really only the children know how to properly
interpret their status property strings.

Right now all existing drivers only understand "okay" versus something-
that's-not-okay, so they all use the new ofw_bus_status_okay() helper.

51dbd04609 Convert from using fdt_immr style to arm_devmap_add_entry() to make
static device mappings.

This SoC relied heavily on the fact that all devices were static-mapped
at a fixed address, and it (rather bogusly) used bus_space read and write
calls passing hard-coded virtual addresses instead of proper bus handles,
relying on the fact that the virtual addresses of the mappings were known
at compile time, and relying on the implementation details of arm
bus_space never changing.  All such usage was replaced with calls to
bus_space_map() to obtain a proper bus handle for the read/write calls.

This required adjusting some of the #define values that map out hardware
registers, and some of them were renamed in the process to make it clear
which were defining absolute physical addresses and which were defining
offsets.  (The ones that just define offsets don't appear to be referenced
and probably serve no value other than perhaps documentation.)

7a22215c53 Fix undefined behavior: (1 << 31) is not defined as 1 is an int and this
shifts into the sign bit.  Instead use (1U << 31) which gets the
expected result.

This fix is not ideal as it assumes a 32 bit int, but does fix the issue
for most cases.

A similar change was made in OpenBSD.

515cbe8673 Call initarm_lastaddr() later in the init sequence, after establishing
static device mappings, rather than as the first of the initializations
that a platform can hook into.  This allows a platform to allocate KVA
from the top of the address space downwards for things like static device
mapping, and return the final "last usable address" result after that and
other early init work is done.

Because some platforms were doing work in initarm_lastaddr() that needs to
be done early, add a new initarm_early_init() routine and move the early
init code to that routine on those platforms.

Rename platform_devmap_init() to initarm_devmap_init() to match all the
other init routines called from initarm() that are designed to be
implemented by platform code.

Add a comment block that explains when these routines are called and the
type of work expected to be done in each of them.

3110e7eed8 Move remaining code and data related to static device mapping into the
new devmap.[ch] files.  Emphasize the MD nature of these things by using
the prefix arm_devmap_ on the function and type names (already a few of
these things found their way into MI code, hopefully it will be harder to
do by accident in the future).

99af02e3b6 Retire arm_remap_nocache() and the data and constants associated with it.
The only remaining user was the code that allocates bounce pages for armv4
busdma.  It's not clear why bounce pages would need uncached memory, but
if that ever changes, kmem_alloc_attr() would be the way to get it.

7bf9ab5331 Merge the FDT versions of initarm.
The copies of initarm used on platforms with FDT support were almost
identical. The differences were pulled out into separate functions that
were called by initarm.

This change merges the, now identical, copies of initarm and a few of it's
support functions. This is a step towards a common kernel on ARMv6.
