afe43c7b5f The versatile platform had two copies of a bus_space that are essentially
duplicates of the standard arm base bus_space, so just use it.

110e70ba1d For some reason, all the arm bus_space functions that work with uint16
values have armv4 in the name.  There's nothing armv4-special about them,
so just use the same sort of names as all the other functions.

4098ccafa4 Revise the arm bus_space implementation to avoid dereferencing the tag on
every operation to retrieve the bs_cookie value almost nothing actually uses.

The bus_space struct contains a private data pointer (poorly named bs_cookie,
now renamed to bs_privdata) which is used only by a few old armv4 xscale
implementations.  The bus_space functions were all defined to take this
value as the first parameter instead of the bus_space_tag_t, requiring all
the inline macro and function expansions to dereference the tag to pass it
to another function, which never uses it.  Now all the functions take the tag
as the first parameter and retrieve the privdata if they need it.

Also fix a couple bus_space_unmap() implementations that were calling
kva_free() instead of pmap_unmapdev().

40e6bdaf1e opt_global.h is included automatically in the build. No need to

f07894dbde Don't destroy bus_dma maps created by bus_dmamem_alloc(). In some cases,
don't create a map before calling bus_dmamem_alloc() (such maps were
leaked).  It is believed that the extra destroy of the map was generally
harmless since bus_dmamem_alloc() often uses special maps for which
bus_dmamap_destroy() is a no-op (e.g. on x86).

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.

59c993d121 Move all the files named foo/common.c to foo/foo_common.c, as
appropriate for each of the 'foo' in the tree. This will allow us to
compile them together (although symbol conflicts prevent us from doing
that today, this just fixes the file name collision).

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.

Fix race condition in DELAY function: sc->tc was not initialized yet when
time_counter pointer was set, what resulted in NULL pointer dereference.

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.

69d75558a7 Remove all #include <machine/pmap.h> from arm code. It's already
included by vm/pmap.h, which is a prerequisite for arm/machine/pmap.h
so there's no reason to ever include it directly.

396e0d581d - Fix IMAPx registers values calculation
- Initialize SMAPx registers too although they're unused in QEMU
- Do not pass IO/MEM resources to upper bus for activation, handle them locally.
    Previously ACTIVATE method of upper bus was no-op so nothing bad
    happened. But now FDT maps physaddr to vaddr and it causes
    troubles: fdtbus_activate_resource resource assumes that
    bustag/bushandle are already set which in this case is wrong.

fdc5dd2d2f MFcalloutng:
Switch eventtimers(9) from using struct bintime to sbintime_t.
Even before this not a single driver really supported full dynamic range of
struct bintime even in theory, not speaking about practical inexpediency.
This change legitimates the status quo and cleans up the code.
