79690a92d0 Add gpio and clock bits for A10/A20's EMAC ethernet controller driver, such as:
- EMAC gpio configuration
- EMAC clock activation

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.

979d76c948 Remove STARTUP_PAGETABLE_ADDR from the ARM configs and replace it with
memory at the end of the kernel.

This helps reduce the SoC and board specific configuration required.

358018a688 Switch to using arm_devmap_add_entry() to set up static device mapping.
This eliminates the hard-coded max kva and roughly doubles the available
kva space.

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.

6489412064 Remove #include <machine/frame.h> from all the arm code that doesn't
really need it.  That would be almost everywhere it was included.  Add
it in a couple files that really do need it and were previously getting
it by accident via another header.

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.

Thanks to alc@ for pointing this out.

696ec285aa Bring initial support for Allwinner A20 SoC (Cubieboard2).
Add support for A20 timer.
	Correct interrupt offset depending from chip.
	Add basic code for CPU configuration module.
	For now, add kernel config and dts file
	(only FDT blob related problem needs to be solved later in
	order to have one kernel for both cubieboard1 and 2).

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.
