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 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.

MFC r259728, r260752

Add Freescale i.MX515 vt(9) driver.

MFC r257383, r257384:

Add some bare-bones support for enabling usb and usbphy clocks.

Add a "no-op" USB PHY driver for imx-family SoCs.

MFC r257197:

Maximize available kva space by doing static device mapping from the top
of the address space downwards, and then returning the lowest mapped
device address from initarm_lastaddr(). Premap most of the device's
on-chip peripherals.

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

Rename imx_machdep.c to imx51_machdep.c, because it contains hardware
addresses which are specific to the imx51 chips.

Rename the existing std.imx and imx.files to std.imx51 and files.imx51, to
pave the way for adding imx6 support.

Integrate Efika MX project back to home.
