393538e6d2 RealView: Move more device address definitions to board-eb.h
The upcoming PB11MPCore and PB1176 have different memory maps and some

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.

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

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.

All the SAM9 boards supported by mainline and the AT91 patches have
been converted to the new-style UART initialization.  Therefore drop

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().

3760f73671 i2c: Convert most new-style drivers to use module aliasing
Based on earlier work by Jon Smirl and Jochen Friedrich.

Update most new-style i2c drivers to use standard module aliasing
instead of the old driver_name/type driver matching scheme. I've
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
patch later.

92b913b08b [ARM] Orion: fix ->map_irq() PCIe bus number check
The current orion5x board ->map_irq() routines check whether a
given bus number lives on the PCIe controller by comparing it with
the PCIe controller's primary bus number.  This doesn't work in
case there are multiple buses in the PCIe domain, i.e. if there
exists a PCIe bridge on the primary PCIe bus.

This patch adds a helper function (orion5x_pci_map_irq()) that
returns the IRQ number for the given PCI device if that device has
a hard-wired IRQ, or -1 otherwise, and makes each board's
->map_irq() function use this helper function.

3760d31f11 ARM: OMAP2: New DPLL clock framework
These changes is the result of the discussion with Paul Walmsley.
His ideas are included into this patch.

Remove DPLL output divider handling from DPLLs and CLKOUTX2 clocks,
and place it into specific DPLL output divider clocks (e.g., dpll3_m2_clk).
omap2_get_dpll_rate() now returns the correct DPLL rate, as represented
by the DPLL's CLKOUT output. Also add MPU and IVA2 subsystem clocks, along
with high-frequency bypass support.

Add support for DPLLs function in locked and bypass clock modes.

5a3a388fbe ARM: OMAP: Timer32K: Re-organize duplicated 32k-timer code
On OMAP2/3, the gp-timer code can be used for a 32kHz timer simply by
setting the source to be the 32k clock instead of sys_clk.

This patch uses the mach-omap2/timer-gp.c code for 32kHz timer on
OMAP2, moving the logic into mach-omap2/timer-gp.c, and not using
plat-omap/timer32k.c which, for OMAP2, is redundant with the timer-gp
code.

Also, if CONFIG_OMAP_32K_TIMER is enabled, the gptimer-based
clocksource is not used.  Instead the default 32k sync counter is used
as the clocksource (see the clocksource in plat-omap/common.c.)  This
is important for sleep/suspend so there is a valid counter during
sleep.  Note that the suspend/sleep code needs fixing to check for
overflows of this counter.

In addition, the OMAP2/3 details are removed from timer32k.c leaving
that with only OMAP1 specifics.  A follow-up patch will move it from
plat-omap common code to mach-omap1.

bee036b503 [ARM] 4886/1: Orion: grab ts209 ethernet MAC address from flash
The bootloader on ts209 Orion boards doesn't configure the right
ethernet MAC address into the GigE unit on boot.  The only way to
get the MAC address is by parsing it from the 'NAS Config' flash
partition, which is an ext2 partition that contains a file which
holds the MAC address in plain text (format "xx:xx:xx:xx:xx:xx\n")
-- this patch does that.

4fd9212cb9 [ARM] 4908/1: [AT91] RTT platform_device fix
The RTT-as-RTC driver will search for the user-specified RTT
peripheral via ID number (0 .. 1).
Therefore if the processor only contains a single RTT peripheral, we
need to set its platform_device.id to "0" instead of "-1".
Also add the missing platform_device resource for the CAP9 processor.

724ce5ee15 ns9xxx: prepare for adding support for Digi ns921x processors
The hardware team changed some things that were taken as being common to
all ns9xxx processors up to now.

This patch addresses:

- irqs: s/IRQ_/IRQ_NS9360_/

- system module registers: some registers are still general, their
  definition lives now in include/asm-arm/arch-ns9xxx/regs-sys-common.h.
  The ns9360 specific ones are in .../regs-sys-ns9360.h
  As a result ns9360_systemclock cannot be static inline any more as its
  definition needs regs-sys-ns9360.h.  This becomes a real problem when
  adding support for ns9215 as this will need regs-sys-ns9215.h and
  including both files will not work.  For the same reason
  ns9360_reset() is now non-inline and gpio functions live in their own
  file.

- register mapping: s/ns9xxx_map_io/ns9360_map_io/

- timer registers:  move time.c to time-ns9360.c;
  s/ns9xxx_timer/ns9360_timer/

72e7ae8141 [ARM] 4823/1: AT91 section fix
Fix section warning:

 WARNING: arch/arm/mach-at91/built-in.o(.text+0xd74): Section mismatch in reference
        from the function init_programmable_clock()
        to the function .init.text:at91_css_to_clk()
 The function  init_programmable_clock() references
 the function __init at91_css_to_clk().
 This is often because init_programmable_clock lacks a __init
 annotation or the annotation of at91_css_to_clk is wrong.

In this case the only calls to and from init_programmable_clock()
are from code marked as "__init", so this fix is trivially correct.

86260f9873 [ARM] 4824/1: pxa: clear RDH bit after any reset
According to PXA300/310 and PXA320 Developer manuals,
the ASCR[RDH] "bit needs to be cleared as part of the software
initialization coming out of any reset and coming out of D3".
The latter requirement is addressed by commit
"c4d1fb627ff3072", as for the former (coming out of any reset),
the kernel relies on boot loaders and assumes that RDH bit
is cleared there. Though, not all bootloaders follow the rule
so we have to clear the bit in kernel.

We clear the RDH bit in pxa3xx_init() function since
it is always invoked after any reset. We also preserve D1S, D2S
and D3S bits from being cleared in case we invoke pxa3xx_init()
function not from normal hardware reset (e.g. kexec scenario),
so these bits can be properly referenced later.

ec7748b59e ide: introduce HAVE_IDE
To allow flexible configuration of IDE introduce HAVE_IDE.
All archs except arm, um and s390 unconditionally select it.
For arm the actual configuration determine if IDE is supported.

This is a step towards introducing drivers/Kconfig for arm.

e27a93a944 ARM: OMAP1: Misc clean-up
This patch cleans up omap1 files to sync up with linux-omap tree:

- Remove omap-generic MMC config as it should be defined in board-*.c files
  instead of using board-generic.c
- New style I2C board_info from David Brownell <dbrownell@users.sourceforge.net>
- Init section fixes from Dirk Behme <dirk.behme@googlemail.com>
