There seems to be some problem with at-least the S3C2440 and
bus traffic during an reset. It is unlikely, but still possible
that the system will hang in such a way that the watchdog cannot
get the system out of the state it is in.

Change to making the code that calls the watchdog reset run from
cached memory so that instruction fetches have quiesced before the
watchdog fires.

This patch separates the current code into i.MX2 and i.MX3 and modifies

 - make i.MX3 compile again
 - fix some structure names to be conform with all the shared/common

 - stay conform to other Kconfig files (note from Russell King)

ad48ce74f7 [ARM] 4989/1: [AT91] SAM9 ClockSource / ClockEvents
Update AT91SAM9/CAP9 PIT driver to use generic time and clockevent
infrastructure:

 - Clocksource gives sub-microsecond timestamp precision, assuming
 memory is clocked at over 16 MHz.  It's less than a 32 bit counter,
 unless it's is also generating IRQs.

 - Clockevent device supports periodic mode only; no oneshot
 support from this hardware.  No IRQs generated unless it's the
 active clocksource.

Later, another timer (probably from a TC module) can provide a oneshot
clockevent device to get NO_HZ and High-Res-Timer behavior.

This also updates the timekeeping to use the actual master clock rate
on the system, instead of compile-time <asm/arch/timex.h> constants
matching what Atmel's EK boards use.  (Product boards may well differ!)

Plus cleanup:  rename "*_timer*" symbols to "*_pit*" (there are other
timers, but only one PIT); shorter lines; remove needless CPP stuff;
make several symbols static; etc.

11aadac4f6 [ARM] 4982/1: [AT91] Drop old-style UART initialization (Part 1)
All the SAM9 boards supported by mainline and the AT91 patches have
been converted to the new-style UART initialization.  Therefore drop
support for the old at91_init_serial() interface for SAM9.

at91_uarts[] array can also be marked as __initdata.

The warning that no serial-console is defined moved from
at91_set_serial_console() to at91_add_device_serial() since the whole
point is the board-specific file is not calling
at91_set_serial_console().

Update most new-style i2c drivers to use standard module aliasing

left the video drivers apart (except for SoC camera drivers) as
they're a bit more diffcult to deal with, they'll have their own
