MFC r283547:

Ensure that all arm kernel configs contain ALT_BREAK_TO_DEBUGGER and not
BREAK_TO_DEBUGGER if they have a serial console (most do). A burst of
serial line noise (such as unplugging a usb serial adapter) can look like
a break and drop a working system into the debugger. The alt break sequence
(<CR>~^B) works fine on both serial and non-serial consoles.

MFC r279850:

Remove MODULES_OVERRIDE="" for Marvel-based armv5 systems.

Also add some #NO_UNIVERSE to configs that essentially duplicate DB-88F6XXX.

MFC r276004: Fix the indentation to simplify comparing the ARM config files.

Disable debugging-related options in all ARM kernel configs for stable-10.
This is a direct commit to stable-10. The following options are disabled
in all arm kernel configs:

DEADLKRES
DIAGNOSTIC
INVARIANTS
INVARIANTS_SUPPORT
WITNESS

MFC 263301

In kernel config files, it is supposed to be 'options<space><tab>' not
'options<tab><tab>', per long standing (but recently not so strictly
enforced) convention.

MFC 263245: Make all the comments '# ' and align to same column.

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.

imx6: Add a tunable to set the number of active cores, enable SMP by default.

ffec: Fix multicast filtering.

Allwinner a10/a20...
- Add gpio and clock bits for A10/A20's EMAC ethernet controller driver
- EMAC gpio configuration
- EMAC clock activation
- Add Static Random Access Memory controller driver for A10/A20.
A10/A20's SRAM is used by devices, such as CPU, EMAC,
for extra fast memory or as cache.
- Add EMAC 10/100 Ethernet controller driver for A10/A20.
It is available mostly in A10 devices like Hackberry, Marsboard,
Mele A1000, A2000, A100 HTPC, cubieboard1 and A20 device
like cubieboard2.
TX performance can be improved using both channels 0 and 1.
RX performance is poor and needs improvement with the assistance of
external DMA controller in case there
- Add EMAC and SRAM controller entries to FDT.
- Add EMAC device to kernel config files and enable EMAC, SRAM drivers.

OMAP: When calculating the MPU freq, make sure not to overflow.

Vybrid:
- Add driver for Port control and interrupts (PORT).
- Export panel info to DTS
- Reset all the layers before setup first one
- Enable display

nandfs: Slight code reordering to make error branch last.

Add option TMPFS to arm/conf/DEFAULTS, remove it from the few configs
that have it individually. Concensus on freebsd-arm@ is that it should
be included in all ARM kernels.

Fix the arm sys_sigreturn(): its argument is a struct ucontext, not a
struct sigframe containing the struct ucontext.
