Add inline implementations of arm bus_space_read/write_N().

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

Use the explicit member initializer style to init the bus_space struct.

Use arm/bus_space-v6.c for all armv6 systems

Consolidate many identical implementations of bus_space to a single
common tag and implementation shared by armv4 and armv6.

Micro-optimize the new arm inline bus_space implementation by grouping all
the data the inline functions access together at the start of the bus_space
struct so that they all fit in a single cache line.

MFC r273258:
Make the ti_mbox and ti_pruss drivers optional.

MFC r273257:
Add a driver for the TI watchdog.

The TI watchdog timer is present on BeagleBone's. Since 2014, U-Boot
has been booting the BeagleBone with the watchdog enabled. We need
to
disable it on boot to avoid a spurious reset.
The timer isn't exactly precise, but it will do as a watchdog. This
is also a reflection of the watchdog(9) API.

In the future, we could handle interrupts, but the watchdog(9) API
needs to be a bit smarter before that can happen.

Adds the ADC driver for TI AM3xxx SoC family.

The ADC has a 12bit resolution and its raw output can be read via sysctl(8)
interface.

The driver allows the setup of ADC clock, samples average and open delay
(the number of clock cycles to wait before start the conversion).

The TSC_ADC module is set in the general purpose mode (no touchscreen
support).

Tested on Beaglebone-black.

Written based on AM335x TRM.

Remove all the redundant external declarations of exception vectors and
runtime setting of the pointers that's scattered around various places.

Remove all traces of support for ARM chips prior to the arm9 series.

Make the default exception handler vectors point to where I thought they
were already pointing: the default handlers (not a panic that says there
is no default handler).

Eliminate irq_dispatch.S. Move the data items it contained into
arm/intr.c and the functionality it provided into arm/exception.S.

Move the exception vector table (so-called "page0" data) into exception.S
and eliminate vectors.S.

Change the way the asm GET_CURTHREAD_PTR() macro is defined so that code
using it doesn't have to have an "AST_LOCALS" macro somewhere in the file.

Arrange for arm fork_trampoline() to return to userland via the standard
swi_exit code in exception.S instead of having its own inline expansion
of the DO_AST and PULLFRAME macros.

Now that the PUSHFRAME and PULLFRAME macros are used only in the swi
entry/exit code, they don't need to be macros. Except that didn't work
and the whole change was reverted.

Remove some unnecessary indirection and jump right to the handler functions.

Use panic rather than printf to "handle" an arm26 address exception
(should never happen on arm32).

Remove the unreferenced DATA() macro.

Remove #include <machine/asmacros.h> from files that don't need it.

262950

Strip arm/conf/DEFAULTS down to just items that are mandatory for running
the architecture.

Move all the files named foo/common.c to foo/foo_common.c

Initial cut for DTS on the hl201 board.

Add commented out dts for sam9260ek as well as early printf support.

Make clock optional on uart nodes, then back it out ("I don't know what I
was thinking, but it is lame.")

Set the baud rate if it isn't 0

Make at91_soc_id() public.

Properly round at91 resource on unmapping.

Move AT91 AIC related stuff to own file.

Fix another bug in multicast filtering. i.MX uses 6 bits from MSB in
LE CRC32 for the hash value, not the lowest 6 bits in BE CRC32.

Follow r262916 with one more config file that references a renamed common.c

Remove bogus AT91 define that causes compile errors. Most of the defines
for SAM9X are going away soonish anyway (once FDT works), but until
then...

Remove all dregs of a per-thread undefined-exception-mode stack.

Rework the VFP code that handles demand-based save and restore of state.

Always call vfp_discard() on thread death.

When a thread begins life it doesn't own the VFP hardware state on any cpu.

Make undefined exception entry MP-safe.

MFC 258211, 257775, 258096,

Add mbox and pruss drivers to ti build.

Use common bus_space-v6 instead of local copies.

MFC r259270

After r266105 ofw_iicbuc.c will be built by default for any kernel which
includes options 'iicbus' and 'fdt'. Remove the (now) unnecessary entries.

Copy head (r256279) to stable/10 as part of the 10.0-RELEASE cycle.

Add support for uarts other than the serial console in TI OMAP SoCs.

The TI uart hardware is ns16550-compatible, except that before it can
be used the clocks and power have to be enabled and a non-standard
mode control register has to be set to put the device in uart mode
(as opposed to irDa or other serial protocols). This adds the extra
code in an extension to the standard ns8250 probe routine, and the
rest of the driver is just the standard ns8250 code.

Merging of projects/armv6, part 10

- Support for Texas Instruments SoCs:
- AM335x
- OMAP4

- Kernel configs, DTS for Beaglebone and Pandaboard
